Terrible customer service and empty promises!!!!!

After my last complaint, Mobile Talk has contacted me to ensure me that the problem will be rectified. It has been 2 weeks and I have not yet received a call to rectify the situation. Instead I receive an invoice with an amount of over R2000 that needs to be paid. I am going to cancel my account and rather go to another service provider. I am unsatisfied with the customer service that we have been receiving and the empty promises as well. I will never recommend Mobile Talk or Telkom to anyone!
