Bad Service!

I booked a groupon voucher but when I tried calling the Crystal Springs call centre I had the phone put down on me 3 times. When I called first thing this morning I was told they are fully booked and they will refund me. My issue is that the first time I called which was on Friday the 25/9 there was no answer. I called 3 times on Monday and after holding on for a total of one hour the phone was directed to a survey for me to rate the consultants service without me even speaking to a consultant. Eventually at 4pm when I tried for the 4th time they were closed. Called this morning and fully booked. Surely if they had answered the phone on Friday or yesterday I would have been able to get accommodation. I must now wait 7 days for a refund. I am extremely disappointed.
