Dont pay a deposit you just might loos it and the deal also probably won't happen

The worst experience i ever had was dealing with we buy cars dome .so i saw a camping trailer i wanted to buy .so as i phoned to find out if it is still available i was told yes it is but wil have to pay a holding deposit so we can get the deal done and it wil be reserved for me so after a week of calling everyday there was always an excuse then its this then its that so afyer 2 weeks i finally gave up as i see on there web site that the trailer has been sold (removed from the site ) and that while the were still so busy according to them to try and get my deal finalized. So then i realized that i wont be getting the deal done so i request that they pay back my deposit i was told i would be done and wil have my money in 72 hours. Well its a week later and still dont have my money forom them after i spoke to the sales guy ,the sales manager and the FNI of the company and as to date my calls get ignored from the sales person and the manager. Probably because they have my number and know its me calling so they dont want to help me as they were not willing to help me from the start and just played games all this time
