New contract and no device

On the 29th of July 2018. I went to Vodacom Brooklyn. I was assisted by one of their new sales representative for new contract. Sale Rep advised me to take the new special which is the huawei P20 Pro that goes with the y6. Initially I wanted the iPhone plus gold. 1.Unfortunately the Huawei P20 Pro was the Out of box repair. The phone had factory fault. 2. I was taking a new contract, they did not change my prepaid SIM to contract I had to do it my self telephonically after 3 days. 3. On Sunday the 5th I took in the y6. The phone was hanging all the time since I was using it in the mean time. Because the out of box failure ended the day before the Technician said yes the phone is hanging and it is not suppose to hanging. He send me to the Sale Rep: The lady she never wrote her name down in all the documents she gave me. Instead she wrote a wrong name. She was so rude and she kept on insisting that the y6 is not faulty even after the Technician said is faulty and they must book it in for repairs. 4. I wanted to cancel my contract since it was less than 7 days and I did not have the device with me. Even now still have nothing. Craig the store manager advanced me not to cancel the contract but instead he will swap the Huawei P20 Pro for the iPhone 8 plus gold and I will pay in the difference. I was sold. He is the store manager and I trusted him as a customer. Until last week Friday the 24th August 18. On Monday the 20th I drove to Brooklyn after calling to check if my phone's are available. When I arrive I spoke to Craig. Unfortunately the colour of the iPhone 8 plus gold was not available. But he assured me that on Friday he will receive stock. On Friday I called him to check if he received stock and he told me he only have the silver and the red. I then told him can't you check with other branches. He said he will get back to me. I call in three times to make a follow up. The first 2 calls he was busy on the other lines and the 3 call he knocked off and he will resume duty on Monday the 27th August 18. Vodacom is that how you treat your customers. It is almost a month with a new contract and no device. I'm really not happy. This was my birthday gift.
