Hisense cellphone problem

Good day

I purchased a hisense emax phone from Ackermans store in Goodwood mall last year in September, i have been having problems with the phone since late last year. The problem is with the charging slot and it doesn't charge full. I returned it back to the store/supplier two times already and this will be the 3rd time and the warranty period is almost over.

The last time i returned it was on the 23rd July and it is not even a month yet and the phone has the same problem again.

It is not my first time purchasing a Hisense cellphone from Ackemans and i never had this kind of problem before. My worry is that the warranty is ending next month and i don't know how long this problem is going to happen and the phone wont be covered. I am not sure if its an ongoing issue they have with their cellphones or what.

I called hisense on the 18/08/21 and spoke to Zandile who advised that i can take the phone back for repairs since it still has warranty and if it still has the same problem and cannot be fixed, they'll have to exchange it or ill have to pay for repairs if i get the same problem again after warranty.

My main concern is that this problem happened few times already, what if it happens after warranty, how will that be resolved, will the warranty be extended.
