Poor Customer Service

In January I was experiencing problems with my Rain subscription and did not have access for weeks despite paying my account. I logged daily Support Tickets which to date have never received a reply. I eventually got through to someone in Sales who suggested I upgrade from the tower to the new router. This was done but my old contract was not stopped. I keep getting billed now for two contracts. Rain arranged to collect my old router one month ago and I'm still being billed for a service I'm not using or even have. Last week I tried to contact Rain via their WhatsApp Number. They told me someone would contact me. It's been a week and I've not heard heard from anyone at Rain. Their Customer Service is shocking. You speak to a chat Bot which replies with the same stupid message. I wonder if anyone will ever contact me from Rain. Their Customer Service is non existent.
