MTN sucks

I am shocked at the poor response time to queries and inadequate format of MTN’s customer service portal. I have logged a query on 2 October 2022 requesting information on data and airtime that had vanished. To date no response to this query, no contact made by anyone. I called in , sent and email and contacted a branch hoping that they could assist. Absolutely nothing. The connection quality has been poor , but the hassle of changing services providers seemed too much. However because of their ridiculously poor service I am considering porting all 3 my number including my business contract to another service provider. I want to know where my air time loaded and data went to? Why is it taking in excess of 2 weeks to respond? There was a clear discrepancy between the information on the app and the call on service that just did not make sense.
