Poor service by RAM

I ordered a Rain sim card and it was supposed to be delivered by Ram. They sent me a message on 6 July that they received my parcel. I immediately called them to change the delivery address. And the agent that helped me confirmed that the address will be changed. On 7 July I got another message saying my package is out for delivery. To my surprise it was delivered to the old address. I informed the driver and also the office called and I informed the agent about the change in address. He apologized and said that he can see on the system that I requested the change. He said he will fix it and my parcel will be delivered the next day. The next day I got another email saying my parcel is out for delivery. Once again it was delivered to the wrong address. I'm getting very frustrated about this because I need this SIM card for my kids online classes. When I track it online it doesn't show the location of the parcel. I tried calling the office and I was on hold for 20 minutes.
