RIDICULOUS SERVICE, AGENTS HAVE NO CLUE!

In the last 2 months, I have sent 22 emails to MTN. I have asked that my problem should be escalated to a team leader / manager. I have sent complaints, but to no avail. I am on contract for MIFI, yet I cannot track my data, as I do not have an MTN phone number, thus I have to pay to make a call. Furthermore, without my knowledge, more money was deducted in the first month, even though I was not notified of it. It took me days to get a reply. I've attempted in registering with the MyMTN application. I could not, as the platform advises that I need an MTN phone number. The service of MTN is ludicrous and I am truly sorry that I have signed a contract with them.
