I spoke with O2 on live chat, as I had an email regarding a refund that was due and needed to provide my bank details (the link via email wouldn’t work). I waited 25mins to get through to someone, to be told it wasn’t secure to accepted bank details over chat, so I’d need to call. I called and spoke with Peter, and couldn’t be verified as I no longer had the number they needed to send a message too (as I’d cancelled the contract and returned the sim!). I was on and off hold for 25 minutes to then be transferred to a company called Scope, who deal with vulnerable customers!!! They told me it happened a lot and apologised. I was furious that I’ve spent the best part of an hour trying to get my refund, and still don’t have it!!!
