Initial good response then Nothing........

After posting a complaint on Hello Peter there was a flurry of activity with two teams arriving on successive days to chect the signal strength and data speed. Both teams agreed that the service was extremely poor and unacceptable. Both said they would report their findings to the relevant departments and there would be some action. To date...... Nothing. Not even a phone call to advise me of the plan of action and a timeline. The service is still most un acceptable as the signal is very intermittent and the data extremely slow. I would like to know if this is the normal way things get done at MTN or am I an isolated case. I hope that there is someone in the company that reads this and cares enough to help find a solution

Thanks

Ronnie
