Barclays PLC Credit Card Complaint

Barclays PLC Credit card department,

Transaction issue Ohio

I booked - nights hotels using the points earned from Wydnham rewards Barclays credit card. The dates we booked are -/-/--/-/- and I received the booking email with the right dates. A few days ago I just noticed that the dates was changed to -/-/--/-/-. I never made those changes. And because of that, I spent countless hours on the phone with Wydnham rewards helpdesk. So many hours wasted on the phone. Changing the dates without our authorization is crime, and Wydnham even changed the date to past!!!
