highly disappointed with telkom

we have a business line with Telkom and the number is *** the line was active from 2018 till 2019 we then encountered problems with the cab on the phone I then took it to Telkom shop in Alex mall for it to be changed. I even went to woodmead also in norwood i made countless calls to telkom but failed to be serviced . the only think that telkom does is to send me messages reminding me of payments now they have charged me R7468.29 this matter has been forwarded to the p&p attorneys . I'm so disappointed with this experience I got from telkom.
