Booking.com complaint: Property Charged more than invoice and charged addl without notification

Booking 2676430014 PIN 7759. Reading the information it did not say the entire amount would be charged but when I booked the invoice read 2149.73 and I was immediately charged $2163.59. I just caught that last night. Yesterday 7:30pm I was notified of a charge from the same company for $66.14 and thought it was a fraud as I had paid in full. I tried all numbers available, texted, emailed and tried again when the agent tersely answered said she could help me then would have to wait until today as the info was on her computer at work. She could not tell me anything – this was disconcerting considering I already got charged more than invoice and now some kind of additional charge. My husband said we better cancel this – we don’t want more unknown charges to keep showing up. Plus the agent was NOT friendly which set the tone for the future – unfriendly unfriendly I canceled last night and informed the agent I expected full refund due to the charges and non information. She tersely replied she wished I had given her a chance etc. I just said perhaps she should be nicer in the future to clients.
