***** on my vodacom contract

I just feel like no one should take a vodacom contract. They help a ******** do a sim swop on my number, helped him upgrade my contract and took a huawei p40 pro. Then I reported this and the ***** department just don't bother to send you some sort of proof that the matter has been resolved. All this things happened at Middleburg mall vodacom shop. I feel like that someone who was helping the culprit had a thing to do with this. This happened in June. Until this day they are quite. How can someone else come in store and do that without a help of someone inside?
