Unacceptable “theft”

I have just booked a hotel through AGODA for an overseas trip. It has been a nightmare from hell of an experience and has totally ruined my excitement. Firstly I booked for 4 nights at the Orchid Hotel, with a free cancellation option. I then needed to amend those dates. When I logged onto my booking, that option to amend dates was no longer there. I emailed them and no one bothered to come back to me. So I had no choice but to cancel that booking! I then rebooked through AGODA again, and chose the room whereby payment was immediate. By the next day, the money was still in my account! So I emailed them asking why the money hadn’t been debited! Low and behold, R598 MORE than the original quote the day before was debited!! When I queried this, AGODA said they would give me 300 Dollars in AGODA money! I thought I would use it towards my next booking. The next day ANOTHER R5000.00 was debited from my account which no one has an answer to why! And the next day they tried to take ANOTHER R4000 out my account, but tG there were insufficient funds! I have now had to cancel my cards so more money is not taken out my account by the ORCHID Hotel in Tel Aviv!
