Lying salesperson - Very disappointed.

I upgraded from my Rain 4G unlimited to Rain One 5G unlimited. The salesperson, OB was his name, promised me that when I received and activated my 5G router, I could call in and have my 4G service terminated immediately without having to pay for both for the month. He also said that he had just assisted a customer in the same situation, and the 4G was cancelled and her two mobile phone numbers were also transferred to the new SIM cards received with the new router. He was very convincing. When I received my 5G Rain One router and tried to do the same, I was told that this was not possible. This means that OB, the salesperson, blatantly **** to me to promptly close a sale. Very devious. I am very upset because I placed multiple call callbacks and wasted a lot of time trying to get in contact with Rain support only to find out that I was pursuing a dead end. By the way, the email *** does not work. I had to call and wait for support to answer. I had to speak to two agents before I could get a straight answer. Yes, OB **** to make a quick sale, and I wasted half my day chasing after his lie. Very disappointing, as I have been a customer for many years. (Rain, please access the recording of the sales call from OB to verify. I clarified this with him 100 percent. There was no misunderstanding. He **** blatantly.)
