pathetic service

My last debit did not go through and my line was blocked. I called the contract dep to settle the matter and the lady was so *********** she could not even answer me one question but instead run to the supervisor. After a long talk with her she said she will get the Acc dep to contact me, they did not contact me and when I did for the 3 time they was busy. Till now my line is blocked. This is so wrong on every level.
