HORRIBLE SERVICE AT TELKOM KOLONADE

I had a problem with my contract phone and It didn't have service I first went to telkom and I was told i need to go to Samsung directly to find out what the problem with my cellphone is I went and I was told it was blacklisted by MTN which genuinely doesn't make sense cause the phone was is a telkom contact phone, I had to go to Samsung and pay a fee of R250 for them to check the phone only for them to to tell me the phone is blacklisted by MTN which doesn't make sense cause the service provider is TELKOM one of the TELKOM consultants told us that it is "LOGICAL ENGLISH" that the phone is blacklisted by MTN we went to MTN and the service was amazing and they explained thoroughly as to what is happening. The telkom Consultant name was SYDNEY the service at TELKOM Kolonade is trash genuinely and they have no respect what so ever for clients
