Most frustrating customer service

Most frustrating customer service .

I am vodacom subscriber on contract. The sim card suddenly stopped working. I reached to "Vodacom Shop Woodmead Retail Park" for a simswap. I made of payment of R70 and was given a new sim and a reference number. It has been two weeks and the sim is not ready. When i called customer care. They told the sim I have been given is invalid and to reach store again. I don't know how long i have to keep following for a simswap. Vodacom did not stop my debit order but I could not use service. I had to pay other service provider for my daily calls. Attached number and reference number below what I have been given in store.

#USELESS VODACOM. FIRST AND LAST TIME IN VODACOM EVER
