5 STARS for the sale, 0 for the service - who is the loser???

On the 15/01/2023 I went into the Vodacom Customer Care store to take out a new contract for my dad. I dealt with a very friendly and helpful lady by the name of Basheera, she arranged everything for me and said when the phone came in someone would call me to let me know so I could pick up, I even wrote a proxy letter informing that my dad would pick up. I watched her write the instructions down, however during the next week we did not hear from them until I called the store on Wed, I spoke to a white female who was rather rude every time I called in since. She advised that she was instructed to order the phone but not to call us. My dad went in and a sim swop was not intended however that is what was done. He was instructed to wait until his sim stopped making and receiving calls then put the new phone on. We waited until Saturday 21/01/2023 and i kept calling but with no joy. Eventually after 3pm that day I called and became Irate and was assisted. What the sales agent failed to inform me was that the debit order would go off 72hours after activation which was the 24/01/2023 leaving my bank account in deficit as there was no funds. When I signed my deal I asked if the debit order would go off with my existing contracts and she advised that it would. Called in today 25/01/2023 spoke to manager Charmaine who I did inform I would be laying a formal complaint as this is the 3rd instance of this store and its inefficiency. The last 2 complaints were not seen to either. Now VODACOM who will pay my deficit? Or does the consumer suffer again???
