Vodacom Terrible service

Our church has been trying to do a sim swop, however we are constantly being given different amounts to pay. Now that we have paid everything we were told, we are now being told that Vodacom has loaded the account for cancellation. We only requested a cancellation quote and no instruction was given that we accept the quote. For every other little thing, vodacom asks for a letter on our letterhead, yet they decide to just cancel. Our Pastor and I have been back and forth to Vodacom, only to be faced with another hurdle. I wish that someone can sort this out. Cell number in question *** . Account B0 142443 -7
