<prompt> Human: Hoping to get some advice here, havent used Reddit much so let me know if Im breaking any rules. I called up my bank to change my address UK and get new cards sent out. I was told everything was done and the cards were on their way.4 days later I still havent received anything, and my security checks are getting rejected, still, so I call them up and ask them why. Turns out they never changed the address, but still sent the cards and PINs to my old address. Obviously Ive started a complaints procedure and, to me, this is a massive breach of security, right? Theyve offered me 100 to resolve the complaint but Im not entirely sure what potential this has. Should I take the money and run? Or is this more serious that I realise and has a lot more potential implications?  <response>: Assuming nothing was taken and you immediately canceled the cards and changed your PINs when the error was discovered, then there shouldnt be a risk, right?
