Shocking Support

I rented a vehicle for 3 days paying up front as usual. A few hours after returning the vehicle I got charged again on my credit card for more than the original ammount with no reversal on the deposit. I phoned up and was assured I would receive a call back within 10 minutes to explain why I was being charged again which never happened. I called again the following day to be be told I was being charged for a 3rd day at a premium rate when my original booking clearly states 3 days on it. Very dissapointed as we have used Woodfords a couple of times recently and were planning on using them as our preferred rental company for all our staff.
