Double Charge on Next Hotel Copenhagen Booking via Booking.com—No Customer Support

I made a reservation at Next Hotel Copenhagen through Booking.com. Later, I received a message asking me to update my credit card information or risk cancellation. I clicked the link provided in the email and updated my details, but my bank didn’t approve the transaction.

However, my friend’s card was charged twice for the same booking, and we have not received any response from Booking.com despite multiple attempts. The customer service number provided doesn’t work, and as I can’t make international calls, I’m left without a way to resolve the issue.

Booking.com, please address this issue immediately, refund the duplicate charges, and provide proper customer support. This situation has caused significant inconvenience.
