DISAPPOINTED LONG STANDING MTN CUSTOMER!

Tried to terminate my MTN contract which is coming to an end via email. I asked for confirmation that it will be cancelled on termination date, last debit order date and value. It is now almost a month and still no response to my email. Customer service sends it on to retentions. After me requesting a response the retentions Team Leader? asks that it be addressed and still no response. No further follow up. Tried emailing again several times....still no response. What I did get.... is a call to on -sell and continue with a new contract. Why would I want to continue a contract where the customer service is non existent. Very disappointed MTN!
