poor response from head office

I am highly disgusted yet again at MTN and the manner in which they treat their customers. I have previously complained to the call centre, store and also had the privilege of getting a call from Theo a member of staff at the regional office. However, I am still a dissatisfied customer and astonished at the response which I got from head office. My initial complaint was where MTN billed me incorrectly because they uncapped my line. I as the customer got pathetic service from call centre as well as store colleagues. So when you think that the issue or complaint in this regard is passed on to a member of staff at the regional head office it might just get resolved. However, all I got from Theo was a sorry..... Sorry for colleagues patronising me, for being held liable to charges that was not my fault, for my line being suspended, for me having to take time out to make calls and also not forgetting making my way to a store, for following it up myself because they never got back to me.... A sorry is pathetic. I requested compensation and get told no, we will just rectify what we did but we will not offer anything else. MTN has the worst service ever and I will let my voice be heard.
