Worst case and store and service ever

I would like to come back once again to write to you as a big concern about Lewis store. We have a debit order as arranged and it went through this morning on the 25 May 2026 yet I got a call that we haven't paid and still got and SMS that our account has been handed over to Lewis store for collections. I have had it with Lewis. The next thing they sent people to my house and claim they didn't now about the arrangements. I have reached the point were I'm going to the Ombudsman to help.
