Poor service delivery Vodacom Baywest Mall

On 31 May 2019 I went to Vodacom Baywest Mall, Port Elizabeth to upgrade my contract to an iPhone XR 256GB. I completed the paperwork and was told the phone will be instore the following Wednesday. Nothing happened. After many enquieries I was told the phone will be instore on Friday. To be safe I went to collect it in Saturday 15 June 2019. I was then informed that the quote I was given had expired - I never asked for a quote - I did an upgrade! Then I was told that my upgrade documents had dissapeared but not to worry, my phone was instore and a new deal will be made. I took my phone and left. The next day while setting up the phone I realized I was given the wrong phone (128GB) I took it back to the store and was then told that they will have to request permission from HQ to reverse the transaction. A few days later I was told the reversal was approved and my phone ordered. Every week I go to find out the status of my upgrade just to be told it was ordered on Sunday - soooo will my phone be ordered every Sunday till Kingdom comes? Prior to all this, I went to Cellucity in Baywest Mall (Vodacom) 14 May2019 and was told that the phone I want was on order and that they will phone me when it arrives - after 2 weeks I decided to try the other Vodacom branch. We have 6 vodacom contracts but I will rather cancell the contract all together than put up with this poor service delivery!!!!!
