RAIN - DISGUSTING ATTITUDE/NO RESPECT FOR CUSTOMER/POOR NETWORK

I ordered my Rain sim card on Monday 28 September 2020. I received my sim on Wednesday 30 September 2020. From the day I started using the sim, i was unhappy with the network. I had complained and was advised that network support would contact me. Rain has a cancellation policy that if you cancel within 7 days, you will receive a full refund. On Wednesday the 7th of October, I tried to cancel the service but I could not use my internet connection, because there was none! I tried calling their customer service with either an answer followed by a dropped call or no answer. And no call back! I finally got hold of someone on Thursday and was advised that they have logged a ticket with their billings department for cancellation and a refund, with a 4 hour turnaround time. To date they have not refunded me! I have made many calls and send many emails. My ticket just got closed now as they said that they have changed the tower that i have been connected to and that there is connection on my sim. Granted I do have connection, but it is interrupted, I cannot make video calls and have dropped signal when i am in meetings, as i work from home. I cannot play music off YouTube or be on my cellphone and work at the same time! I can only use one device at a time! for a so-called Uncapped and unthrottled service. Yes it is beyond their control on the signal i receive as support staff but I have been waiting for a week and a half for them to deliver on their promise, only to be told that my ticket was closed! Absolutely pathetic!
