Credit card — BARCLAYS BANK DELAWARE (OR)

Problem with customer service. I am filing a formal complaint against Barclays Bank and XXXX regarding a wrongfully denied chargeback dispute despite clear and documented evidence supporting my refund request. Additionally, my original reservation amount was {$490.00}, yet this amount was arbitrarily adjusted to {$390.00} without explanation during the dispute process. On XX/XX/XXXX, I arrived at XXXX XXXX, XXXX XXXX XXXX XXXX XXXX, XXXX, AZ, with a prepaid reservation booked through XXXX ( XXXX XXXX XXXX ) for {$490.00}. Upon arrival, I was informed that the hotels water pump was broken, leaving all rooms without hot watera fundamental necessity for a habitable stay. The front desk confirmed this was an unforeseen and unresolved issue, leaving me no choice but to cancel my reservation
