Useless service from Vodacom Business

Requested a new business contract, which was delivered with a sim card which was not of the requested size. Then the sim card is not active/ported and each time I ask for help I have to write and sign a letter and send my ID. I have had to write 4 letters and send my ID and a scan of the sim card each time for one simple contract. Call center staff are as useless and VBS just keep passing the buck.
