Cannot Contact Hotels.com, Refund Still Not Received Despite Confirmation

I am unable to reach Hotels.com through phone or email, despite their claim that my refund has been processed. The money has not appeared in my account, and repeated discussions with my bank confirm that no transaction has been received. Hotels.com provided a bank reference number, but it is useless as the funds are missing. This lack of proper communication and unresolved refund is highly frustrating. Neither the contact numbers nor the email addresses provided work, leaving me with no way to resolve this issue. I demand immediate action from Hotels.com to clarify the situation and ensure my refund is processed without further delays. This level of service is completely unacceptable.
