Gumtree rippoff

I tried to sell my trailer via gumtree. My ad was published and they very keenly took the monies off my Credit Card. Ten minutes later I was notified that my ad was deleted because I did not comply with their standards. Turns out that because I edited my pictures by removing my family members from the pictures...i.e. just leaving the the aforesaid trailer in the pictures....the actual item I was selling...was not up to their ridiculous standards. The worst part is that they responded in such a poor manor that it leave much desired. Oh...and by the way....you monies will be return to your account in 10 days.....
