Wrong figures on account and very bad network

have complained on this forum a while ago about my account falsely regarded as outstanding. I am still bombarded by computer messages and sms messages. The amounts vary. My account is paid up to date. Nobody phoned me yet. I also lodged a complaint regarding bad network coverage to a large group of people. Instead of attending to the needs of their customers who pay monthly for poor service, they are busy with a lot of nonsense. Sometimes one has to make four to five calls to finish one conversation. Is it because poor black people are living there?
