MTN does not deliver on anything

I took out a contract with MTN a few years ago after they had assured me that there is no problem with signal strength in my area. <br> <br> I soon discovered that the MTN signal is nonexistent for recurring periods every single day. <br> <br> The problem has been reported to the local office several times, the last being a week ago. I have also, on numerous occasions, sent e-mails and also lodged complains on their website. <br> <br> I receive acknowledgement of receipt and promises of feedback every time, but that is where it stops. A mechanical device sending a message, never a real person to see to the problem. <br> <br> Last month the account was double its normal amount, when I queried this I was told that they will send me a detailed statement and debit me with about R30, which I reluctantly agreed to. It's a week later and nothing has been received. <br> <br> I have also asked them many times to not send me sms messages, but to use my email. this they also ignore. <br> <br> My experience with MTN is totally negative, they do not communicate at all. <br> <br>
