MTN biggest ***** company with zero assistance or answers

For 24 years we had a contract on debit order with zero payment problems. Sept the 3 phones on the contract stopped and when we enquired it was said due to non payment. Only to realize someone inside MTN changed the main nr and stopped the debit order. A case of ***** was logged. Affidavits etc was sent but up to now we are still without phones and zero assistance from MTN. It's so bad that someone from "*****" contacted us out of nowhere saying they've found the problem but as all the ****s go ....need to log in to your bank to give them a code etc. Just shows how *******ed MTN are. For 2 months now I've paid via eft. I am stopping payments now until we get an answer.
