Nonsense service

Worst experience ive had, took out a month to month contract for lte. The device has not been delivered and i cant track it as DSV says theyve been calling me only to find out that the number they have been calling that they were given is a number i stopped using more than 10 years ago. Now i am calling mtn to assist me but they can not as they can not authenticate me what the hell is really going on these days. When buying these services they call you back to back to make sure you buy once you pay they run no man no.
