mtn dont care about their loyal customers

so it has been 3 weeks now since i have paid my account in full to mtn after they suspended it and refused to contact me since there is no way of getting in contact with their legal department for 3 months i have called and even emailed but they ignored me and now i have payed my account up in full and they still will not reconnect my phone and i know for a fact that they will bill me for this month that i have not used their service but still they ignore me. i have been a loyal customer of mtn for the past +15 years and this is how you treat your customers.
