MTN

Never been so disappointed as I am towards MTN. I "HAVE"been a loyal customer for almost 20 years. Never skipped a payment. Phoned MTNo get a cancellation amount on one of my contracts , paid it to the cent, phoned them to tell them about the payment. They went and allocate it towards my current account payable by debit at the end of the month. Now they say that there is not enough money to cancel my contract! Spent hours on the phone and made numerous calls, just to be ignored of the call being dropped. The latest email not been read in 36 hours. Today I spent my whole lunch hour on the phone and in total made 11 calls today to try and speak to account to correct. Maybe Vodacom treats the customers better - I am surely considering going the change. How do I get help ????
