TIFU by trying to buy a gpu online behind my parents

I recently tried to buy a used rx 580 online in my country from a nearby city, I've always been wanting to build a pc because all my entire life I've been using a phone and I got a laptop last year but it was old and slow, nevertheless I was still quite happy with it and I've actually learned how to code with it and started to make a game a few weeks before something horrible happened, because of how old the laptop the hinges gave up and the screen couldn't stand anymore.

I didn't mind it and made a stand for the screen until turning it on one day it began glitching and stuff, after going to a PC shop they determined it was faulty ram, I had two choices right there and then, either buy new ram sticks and use the outdated laptop or save up for months to get a better laptop or getting a PC, I decided to not suffer the slowness of the laptop and save for something else, that's when I began saving my school allowance for basically eternity, I didn't even get chips or snacks or drinks for months basically, I had the lifestyle of a hobo and I constantly did favours for my parents to get more money.

fast forward to about a week ago, I decided it was time to start getting the parts, my mom owed me some money so I thought I'd get half of the parts for the PC now and the other half in march when my mom would give me what she owes me, I went to find a good but affordable gpu in my place's Facebook market because most people aren't the smartest in prices in my area, but it'd soon turn out someone was a bit too cunning for that.

I found the gpu that I wanted for the price and he was a far from me quite a bit, we talked until I paid him the equivalent of 60 usd dollars in my country which mind you, took around 2.5 months to save up for with my allowance, I paid him on last week's friday and supposedly was getting it on Wednesday, we exchanged contacts and then I waited for Wednesday and when it came around for the time he said I'll receive the call, I got nothing.

I waited an hour still nothing, I went back home thinking he might had forgotten but he stopped replying to my messages, hours pass by, days, and finally today on this week's friday I see that he read my messages however to my shock he actually blocked me on the app, what's worse of all is because of paranoia, on Tuesday I deleted the contacts as I feared my parents would question about the new numbers I have on my phone because on the same day they'd caught me recharging my data plan for calling and they thought I'm calling strangers for illegal stuff (I don't know how that even connects together), but now that he blocked me I couldn't even call him because I lost his number what's worse is he deleted the message too for his number, the only number left was the one that I sent the money to, which up searching on it on a number verification website turned to have the name "you won't know me".

which literally felt like a spit in my face and something comedic.

because if I even thought before hand to look up the number I would had seen this, now the money for my gpu is gone and I have to wait till may or early june again to save up or somewhere around those times to what I lost.

I just kinda wanna tell my parents but I'm doing this behind their backs because some small part of my money is taken from them directly instead of the allowance, so yeah, I wish I could refund the money but I already sent it and it's been around a week so I don't think I can do anything about it, I know it's only 2-3 months at most till I make that money again but the past months have been hell on my mind because I literally couldn't do any of my favorites hobbies.

I really wanna go back to coding game or silly mods for games but with how everything is going my hands are tied and I'm getting impatient, I thought 1 more month couldn't hurt but because of the gpu dude I've gotta wait now even more just to do anything I like, it just feels absolutely boring to not have anything else fun to do.

TL;DR: Don't buy shit online if you don't know what you're doing as a teen especially if it's behind your parent's backs. otherwise it could set you back months for the thing you wanted.
