Vodacom your assistance is required

I just hope someone could assist me with the over billing of my vodacom account and the over chargers. I have even message the CEO of this business. Hopefully I will get some answers. A lady from your Durban office by the name of Debbie was to sort this matter out but she never even come back to me. The call centre just keep putting me on hold or the call is dropped. It's my 4th review on hello peter
