Unsatisfied

I bought a pre owned iphone 11 from truworths gateway, with consultant funna he advised me the warranty and if it should be broken or have any issues I can return only if not taken somewhere to be fixed After 1 month of purchase phone starting going blank I took it in he said it will take over a month to be fixed or nor sure if they will so I took it back home because I could still use it

On the 9th September I took it In and they sent it to mtn then mtn did not fix but sent to store Today I get a call that they can't fix and it picks up that the phone wax fixed by someone else so they can't fix or refund I paid 9600 for the phone which was 1600 of 6 months today the phone is not working which was because it's preowned and previous owner could have fixed it and sold it then the phone was not accessed before being sold to me I don't get the phone fixed or refund or exchange Long as the truworths account is paid they happy to have sold a broken phone to me
