NO help after complaint

I had trouble getting hold of someone to assist with application for new line as call center does not answer and getting missed calls after ringing once from the online department call back feature. A lady contacted me to assist with application after submitting complaint, I had an account with mtn previously that has been settled but is however still showing up as legal. The lady assured me she would submit a request to purge the account and then we can proceed with submitting the application as doing so when the status has not been changed will cause it to be unsuccessful. She then contacted me back days after stating she had received no feedback and would be submitting the application as is. I then received a sms saying it had been unsuccessful. I feel that on her side it was not a smart choice and that nothing was really done to help me. I have since then contacted the legal department myself to have the status changed and was told to contact sales again. This has been a nightmare! so tired.
