Zero response, ZERO customer service!!

On the 6th of April I sent an E-mail to Busisiswe Matlala (***) asking why my monthly rates bill increased from R783 to more than R2600, but of course no response, just another invoice in may which has reverted to the usual R783. I'm not really surprised, as this is what we have been forced to accept in this country, but nevertheless, I want to put it out there, especially with the name of the person that actually does not give a flying hoot about the customer.
