BAD SERVICE

My fiancee took 2 phones contracts with Telkom in 2016 Sep.one of the phones malfunctioned 2018 Feb.took it back I was advised warranty is a year so we let it go.we took another phone contract in May 2018,2nd week my phone fell & cracked the screen but was still functioning properly . 1st week July the phone requested for a software upgrade & I did it.The phone went off and never switched on.I took it back to Telkom and it was booked in for repairs,after a week we got an sms that we need to pay repair fees of R3000 what the ****.How can we pay repair fees of R3000 yet the phone on its own costs that much.The phone malfunctioned on its own not because of the screen and we have 3 contracts with Telkom but we still getting ****py service.2 of our contracts are expiring this year,we were planning on Upgrading but after this BAD SERVICE.we'll be moving to another service provider.cause clearly we not good enough for Telkom. We'll be cancelling the remaining contract as well
