PAYMENTS NOT ACKNOWLEDGED

Initially my contract was with Nashua Mobile, in November 2014 I was transferred to MTN & that's when my nightmare began. In the 2nd month I called the contact center to update my banking details with no luck, i went to the branch & I was advised that my account had been locked I then made a payment which was not acknowledged. I later made 2 payments on separate dates only after the 3rd payment I received a letter with no mention of the payments i had made. From the beginning of April I started sending emails to customer care & the Legal department & up to date my issue is not resolved & all I have been asking for is an updated invoice.<br> <br> 3 Weeks ago I received an SMS stating that my account has been handed over to VVM, I called them but their service is also appalling just like MTN. <br> <br> I took a contract with NASHUA to avoid this.
