Poor return policy

Poor experience with trying to trace and retrieve the copy of the till slip, I purchased a Hisense 58” TV on my Game RCS account in 2022, the TV all of sudden switches off a few seconds after switching it on. I contacted Game call centre and they said i need to retrieve the RCS statement which i’ve done in order to retrieve the till slip in store, but when i arrive in store i get told that they are not allowed to retrieve copy’s of till slips older than 3 months regardless if i have my RCS statement for proof of amount purchased on my account with the date of purchase

i’ve been battling for weeks trying to get Game to help me out with this matter but it’s backwards and forwards and i need to have my TV fixed as it’s still under warranty but clearly they don’t seem to care at all
