Pathetic fobbing customers off.

I have contacted Vodacom without success to find out why I am receiving calls from their customers querying accounts. The call I receive are from users who have phoned Vodacom help line and either told to hold on and then somehow my phone rings and they speak to me , or they choose the account option and the call comes through to me. This is on my private number!!!!! I don't work for Vodacom and they need to fix this story. I am tired of being advised that they will look into the matter. Next step is a complaint to ICASA.
