RAIN internet service is the worst

I cancelled my contract on the 23rd of June 2022. I got a response confirming my cancellation with ref number. My last payment was supposed to be July 2022. I got debited in August 2022 as well. When phoning the call centre,I was told that the contract was cancelled but the line was not closed. They will escalate it. I got a confirmation email of my refund that will be done in 7 to 10 working days. 11 days later I phoned and was told my query will be escalated again. A day later I got a response that a refund will only be done once the router has been collected. The collection of the router was confirmed on the initial cancelation but no one contacted me, one the 1st escalation, the confirmation email also stated that the logistics department will contact me to collect the router but Noone did. I am not left with a financial predicament all cos I was debited and no where did anyone tell me that the account is not closed or that refunds will only take place once router is collected. I have been promised of a refund but this has not happened. This is utterly disgusting. I had reference to all communications specially the confirmation that I will be refunded and with no reference to ,refunds will only take place if the router has been collected. You took my last money for a service that I cancelled 3 months ago.
