Rain is a nightmare

I have been receiving phone calls from CCD courier company stating that they have been instructed to collect my Rain router on the 24th of April 2023. I however could not understand why they would just want to collect the router when I have not queried that it was faulty or any other. I notified Rain about the call from the courier company and then was assured this matter has been handled and should not expect any further calls from the courier as I also stated. Today 25th April 2023 I received another phone call from the courier to collect the router after I was promised this matter has been sorted. Then my debit order goes of exactly on the 25th of each month and this month it never went off my account without any explanation but I get annoying massages that I am behind on my payment. I couldn't for the life of me understand what is happening at Rain or do they know what they are doing? It is so frustrating that Rain is such a pain constantly and provide people with such poor service, yet we pay them. I have enquired why they never debited my account this month and no one is getting back to me and there is such a poor connection to their network whereby you need to submit tickets until you blow arteries. Rain your apologies seems to be just words that you use and there is no progress in your service, this is unacceptable that you just don't give a hoot.
