Vok & van Zyl has no service

I was referred to Vlok & Van Zyl by a friend 2 years ago. Some time after, my friend told me to drop them as they started invoicing left right and centre for items never agreed upon. The service in general was bad and communicating non existent. I did not move away at the time but now it has become clear that i need to run. Sarel who is a managing partner does not communicate unless money is owed, when a statement is queried with items on that was never requested i am told to pay because that is what is owed
