Terrible service and wrong billing

<p>In March 2016 my cellphone contract was taken over by GloCell and I did an upgrade also during March. I took out a TopUp contract and they confirmed that the costs won't go over R103-00 per month. Last month I received an account of R197.36 and this morning I received my new statement to the amount of R829-56!!! How is this possible on a TopUp contract?! I tried to phone them on numerous occasions but they just don't answer. Last month I lodged a written complaint to GloCell and on HalloPeter but till today nobody responded. They do not keep up with the agreed upon contract and I want to cancell my contract because I cannot afford these bills that I receive from GloCell. I specifically took out a TopUp account to avoid getting accounts like this and I have never received such poor service in my life!!</p>
