Room not available despite paying £4000

Booked our honeymoon via Co-operative travel this Saturday. The advisor that dealt with us spoke to a represenatative from Gold Medal who stated the room we would be staying in, the duration of our flights and baggage allowances. We were thinking of going to Mauritus for 2 weeks on our HONEYMOON!!. We paid the company the money for our honeymoon and requested if we could have a sea view facing room, if not didn't matter, the advisor said she would request this and relayed to the Gold Medal advisor. A few days later I rang to enquire about whether our request had been granted. To our amazement....we didn't even have a room to stay at the resort we booked let alone a sea view facing room!! If we wanted to stay there we had to pay an extra £314 as the Gold Medal advisor "assumed" we were making an enquiry and didn't have the initial Deluxe Room!!! We have parted with £4000, needless to say we will be going in on Thursday for a solution to our problem. Either staying at the resort we chose and set our heart on or our money back!! Very disappointed!!
