Failure to reactivate cellphone service

My cellphone service was suspended due to Telkom being late on the deduction for my contract. When they then wanted to deduct the money, which was the following month, there was unfortunately insufficient funds available. The money was eventually paid but my service was not reactivated within the stipulated time frame. I have escalated the issue numerous times and every time I am told that the matter will be escalated. This is really putrid service considering that I work in the I.T field and customer service and going the extra mile to maintain good service delivery is our main objective.
