UNPROFESSIONAL /BAD CUSTOMER SERVICE I RECEIVED

I orderd my Sim card from Rain on Monday becasue I knew that by Friday it would be delivered as I am in JHB and it normal leaves from Isando JHB. In my previous order my adress was Durban. I usually order my sim card online where I can able to change my adress when I place my order but one of the consultants at their call centre told me that they will send me a link to pay because it is faster than me ordering online. I told her I need my adress chamged because it reflects Durban and I am in JHB. I am so upset because she didn't do that. My sim card went to Durban for delivery a. D I am the one who had to keep calling Ram and rain to stop the delivery and get it sent back to Johannesburg after so many attempts of logging a call on their support for them to call me back to assist. They never called and no apologies for their mistake. Today is Friday and my sim card had not arrived and I need to be in another province tomorrow so I won't be able to receive it. Basically I have paid for nothing because now I might have to cancel and get another service provider. I am so disappointed in their conduct. They got my adress wrong after I made myself clear and no apologies whatsoever. All my requests for a call back on their website have not been answered since I placed my order. So they are able to call me back when 8. Red to place an order and receive the link the to pay but after paying no one cares about any queries? I am so upset by this service i got.
