I've just this second photographed the bank statements for the 11th to 13th November 2019 and have PM them to you.... unfortunately they are on three pages and not as I'd like on one page. As I mentioned before I didn't disagree with the refund and was in fact about to ask Fitness4Less for their bank details to make a refund. My point is that Santander did take second over payment without my permission or any contact with me. I also accept that they really shouldn't have done, but in this instance it was ok. Basically I think we are saying the same thing, apart from they do take money without permission and I accept that they really shouldn't have done.
If they take money without permission it is an error. Double payments can slip thru, especially if the bacs service they use had an outage. Normally it’s fixed before anyone notices. Something it’s missed entirely!
