Lazy and distracted sales agent

I have been with Vodacom ever since my very first contract. I understand that being a call centre or sales agent is not easy and that's why I have been patient. But I have had enough. 1st. Upon taking up a new contract, the sales lady was busy making herself something to drink, I was put on hold forever (probably so that she could drink her beverage). 2nd. Two weeks went by and delivery of my still wasn't done. Upon following up on delivery I find out the delivery address is an address I have not lived at for 7 years which means the lady who was making herself some tea was so focused on the tea bag instead of my delivery address that I provided. 3rd. I had to wait for the package to return to the vodacom branch before I could change the delivery address for the phone to be delivered. 4th. Upon receiving the phone FINALLY, there is no sim card in the package of which I asked for because the current simcard i have is so old and damaged it doesn't work!!!

All this happened because of that sales agent. And when I wanted a complaint to be lodged against that agent no consultant wanted to oblige.

I can't deal
