Poor customer service

After calling about 12 MTN stores without any of them answering their phone, I get through to MTN in Fourways. A lady by a name of Mary picks up the phone and I tell her of my query. She takes the details down and write them instead of checking while I am talking to her. I told her that I will hold while she sorts out the query as I have tried calling so many stores and she told me that I must not compare them with other stores \with an attitude\". I hanged up.. She calls me back addressing me as \"sweetie.\" as in \"listen here sweetie\" . I asked her if I could talk to her manager and she told me that the manager was not there and first I called for help and now she calls me and I don't want to talk to her. Can MTN please provide us with better customer service and train their consultants on how to address and assist their clients. The attitude that Mary had was absolutely unacceptable and to call so many times to try and get assistance without getting any.. UNACCEPATABLE SERVICE<br> "
