I made a booking for a property in Tanzania, the property requested immediate payment and I wanted to cansell the booking, the property refuse to cansell the booking so I made arrangements to pay the property a few days later. My booking was canceled on booking.com so I phoned and tell them I already paid the property. They asked for proof of payment so I send a proof of payment as well as the bank statement with the payment reflected, they want the payment in USD so I send proof of the payment that I did via the link that show the USD because the bank cannot make the proof of payment in USD but still they are insisting a bank statement in USD.
