MTN is incompetence at it's peak

At the end of 2015 I changed my email address and notify everyone, including MTN.<br> Since then I do not receive my monthly invoice and statement, which was no problem before the change of email address.<br> I wrote to them, called them and after a long time I was promised it was now rectified. Not so. I started again and was routed round and round to the dreaded call center. They do not listen, just send you back one of the pre-typed emails. Now they want my banking details... yet they are debiting me every month. It is just gross incompetence and arrogance. I think they train them in being as useless as they can. What a disgrace. Incompetence and bad attitude rules at MTN. Do I need to say more? Close to 20 000 complaints at Hellopeter says it all. Just waiting to finish the contract unless they close down before that.
