Telkom Mall of the North

My mother bought two phones on contract at Telkom mall of the north ,one of the phone got lost and we reported the phone after few days the other phone ,started having network from 2022 around march,since then she is been going to Telkom,every month explaining that she is having a problem with the phone ,they would always say she would just take the sim card out tand wait for few minutes the network will be ok and that was not not working as all as the phone will have network just for 2days and it goes back again,now In January 2024 when she goes to the store and tell ,the that she is tired of complaining about one thing over and over ,the story change saying she must take the phone to repairs because it’s been over a year ,and she must take it to the brand shop which is huawei ,due to that they won’t fix it ,since it’s over a year .why would they wait for a year to be over while she is been complaining for over 11 months about the phone?it is bcoz the wanted the year of the contract to be over so she can pay lot of money for repairs?or it how they reap their customers money ,when we buy on contacts.because now huawei charged my mother R1200 to fix the phone that she was not using and paying a contract every month of something that is not working .she does not have that kind of money
