*********** and unprofessional

Recently had a terrible experience with Cell C. They offered me a Black Friday deal, I accepted the offer and the Sales agent advised that he is going to use the address reflecting on my bank statement as a residential address because they are going to need proof address upon delivery, however, the delivery address will be the one where I'm currently staying at. Their smart courier company decided to deliver to the address reflecting on my statement. I contacted Cell C to enquire about this as I was seeing the delivery address on the courier's portal, they assured me that the delivery address is correct I should not worry. I don't know how many calls I made both to Cell C and their courier company trying to fix this but with no success. They are now telling me to re-apply, how do I re-apply when the offer was on promotion at the time. I have been their prepaid customer for more than a decade now, I'm definitely porting out I don't want anything to do with them. The way that they handled my situation is very disappointing and unprofessional
