Worst network

I had lost my job and my cell account went up over R2500 over due which is easy as my basic contract is over R600 pm. I was suspended (not a problem) I them got a job and had my account up to date over 2 months leaving just over R200 to catch up the following month. I contacted customer care and a wile later a lady contacted me and I made an arrangement with her to place debit order on my account and that the full amount plus my outstanding would be debited. Only 3 days later they cut my phone after I thought I was ok and had made an arrangment. I was upset and phoned 3 time and explained and in the end I asked to be put through to cancellations after 3 time the cancellation dep told me I would be contacted. Well it never happend. My phone is up to date now but I want to cancel the contract soon and my contract ends. My Mtn contract never gives me problems. My cell c free minutes build up because the signal is so bad I can almost never make a call and hear what iis being said. Stop buying out other people's contracts and work on improving your network. Thank goodness my cell c upgrade is in December. So improve or I will be canceling
