premium leisure 6 weeks of run around & never got the spa

We tried to purchase a swim spa from Premium Leisure. Received written contract which outlined the terms they wanted us to follow. 3k deposit with 10k due in cash at delivery, We signed and waited for delivery date. after several weeks we contacted the company, they stated they would have a confirmed delivery date within the week, After another week went by we contacted them again, we were told their delivery dept would be contacting us to set up delivery which they did the next day with the promise of yet again confirming a delivery date within the week. Again a week goes by and we call the delivery dept and were told the following thurs or fri our spa would arrive but instead of cash we would need to get a cashiers check.. The Wednesday before delivery we called to find out who the cashiers check should be made out to only to find out the spa did not make the truck and he would get it on the very next truck and get us a confirmation number but know they preferred to have us put the remaining balance on a credit card. So I paid off a credit card in order to make room for the large balance to be put on there. He called the following day stating the next Wednesday the spa would definately be here. Again we took the wed off work scheduled the crane call the night before to make certain it was coming and now they say again it did not make shipment because now we needed to send them a cashiers check to pay in full prior to shipment. After I pointed out my reservations of sending basically cash for this phantom spa that keeps not showing up and reminding them of the contract that they drew up stating cash on delivery. They stated they just could not let the spa leave without payment in full. I offered to put the balance on a credit card or wire funds in full upon arrival or cashiers check upon arrival and none of these options satisfied them. In a nutshell i have spent $1800 on wiring, rescheduled 2 cranes, taken 2 days off of work and am fighting to get my 3k deposit back all for a spa that never came even with a written agreement not to mention we were given the run around for 6 weeks with make believe delivery dates.....This company has no integrity, does not abide by written contracts they create, and shows a complete disregard for the customers they should be serving.....I would seriously think twice before dealing with this unprofessional company. Buy somewhere anywhere else!!!!
