Unacceptable customer service

I had signed up with the holiday club in May 2015 because it seemed very appealing but due to financial circumstances i had cancelled my application within 3 days and had requested a refund for my deposit it is now August and no refund was received. I have to beg for responses and dealt with very unprofessional people in client services that were rude and uninformed. They had told me on email that i would receive a refund by the 10th of August. I queried again when no refund came through and after all this time was told to go ask my bank to do a reversal. THIS WAS THE MOST UNACCEPTABLE AND UNPROFESSIONAL behavior. I would not recommend that anyone sign up immediately with The holiday club if they are not 100% sure and definitely DO NOT PAY A DEPOSIT because they will give you the run around for your money.
