Contacting, paying and cancelling Rain = Mission Impossible!

This provider is shocking! I battled with connectivity and then moved home and wanted to cancel my service. I have been trying to cancel since May 2020. My credit card expired in February so I sent in my notice to Rain, said I was happy to pay up till end of May 2020 so please could they send banking details. They WILL NOT provide an alternate method of payment for me to settle and cancel and I CANNOT pay by card as it has expired! Now we send emails back and forth daily with them saying, "upload card" me replying "sorry I cant how else can I pay?" only to get back an "upload card" response. This has been going on for longer than 2 months now with no end is sight. Unable to contact them via telephone as "call centre is closed".

Need to pay till end of May (notice period) and cancel. Please contact me!!!
