Rain - ****** that debit full amount for service not rendered in full!

I am appalled by how Rain is handling my query. In August 2023 they debited full price from my bank account knowing very well I did not have full service for the month - after I waited 3 weeks for them to swap their faulty router. Now we're in Oct 2023- that router hardly worked 2 weeks and it also stopped working!!! I had no service AGAIN in Oct 2023 from 13 Oct - they only replaced the router on 30 Oct. I asked that they call me to sort out this billing issue - but till now - NO ALL. They are ****** and want to be paid full price for a service that was never rendered in full. Everything with them has to be a fight! This is disgusting! Ref ***7, ***6, ***6, ***2 clearly all these references mean nothing to them. Wow! But watch how fast they will debit my bank account!
