Hi KEB,
I'm sorry to hear that you are frustrated - I thought I would shed a bit more light on the situation.
There is a certain point before a holiday departs that we have to "give back" any unsold flight seats and hotel rooms and the holiday goes into a "request" status.
When this happens, a customer is able to make a provisional booking with a deposit (in this case £100) and our sales team will endeavour to source the flights and hotels as per the rest of the group. There may be additional supplements and you reserve the right to cancel your provisional booking for a full refund of your deposit.
The 5-7 days you were quoted is the maximum time we'd come back to you in and is subject to our suppliers providing us with information in a timely fashion. We do try to contact our customers quicker than this.
Kindest regards,
Julia
