Booked caravan paid deposit, but not recieved confirmation?
I found a caravan to rent on a rental site and contacted the owner to book our holiday for next August. We sent a £100 deposit cheque which the owner cashed on 20th August. I contacted her at the beginning of September to ask when she would send confirmation of our booking and she said she doesn't send confirmation, she emails it so she asked my email address and said she would do it. Last week I contacted her to ask why she hadnt emailed confirmation and she apologised and said her internet was down at the moment and she would send it soon.
The site she advertised on is legit with pictures of the caravan etc but I'm getting a bit worried as we have no proof other than the fact we sent a cheque. Am I right to be worried? Does anyone know the legal view on deposits for holidays?
Help!
Thanks in advance.

Speak to the police, not about return of your deposit because this is another issue. Contact the station close to where the site is, if the site exists, it may be that they do have issues. All sounds a bit iffy to me.
Try a google search for the name of the site, if they exist, you will have some information there, search images too as most people put their holiday snaps on the net. If they are scamming, you may find info on this too.
If they are scamming, file a complaint and have it dealt with through the courts.
You have a good chance of return as you paid by cheque.
