MTN engages theft and Customer abuse

I can honestly say that MTN has the worst customer service and ethics of any company I have ever dealt with in nearly 40 years. Due to its ethics I have sold all my shares in the company, that I have held for over 15 years. I cancelled my contract 5 months ago and payed a penalty to do so. I continue to have money removed from my account by debit order. Complaints requires you to sit on the phone for about 25 minutes (this time, an hour so far) and go through security checks etc. when the call is transfered and you start laying out your complaint you are immediately cut off- Purposely I believe,- as it has happened multiple times. I have written an email and the response I get back is"Please contact us telephonically" What is one to do. This is blatent customer abuse. Theft of money and my penalty that I paid. If they are not cancelling my contract, they can't keep the penalty as well. When you are trying to run 4 businesses, this wastage of time is very costly to all including employees and SARS. MTN has allegedly been involved in ********* behaviour in Iran and Nigeria. I suppose this is the hallmark of the company. Warren Buffet uggests never investing in an ********* company.
