Second time that MTN is giving me NO service at all

I picked up that our business was charged monthly for a contract that we did not know about. These debit orders went off our account for years. After weeks of querying this and MTN sending us incorrect information or ignoring our emails, MTN agreed that they do not have any contract on file for these charges. It is now again weeks and numerous emails later where I am trying to get these funds refunded to our business but MTN ***** department does not even give me the time of day to respond to my emails and they do not take telephone calls. A week ago - I send an email telling MTN that I will go to Hello Peter if they do not respond to my query and again I was ignored. This is the second time that I am in a situation where I (or my company) was de*****ed by MTN and this is the second time that I (after months of trying to resolve the case with MTN) had to go this route in order to get somebody from MTN to talk to me. The after sales service from MTN is shocking and the fact that they allow their customers to be de*****ed and they are not giving ANY support is very concerning for a big company such as MTN.
