I used this company. They asked for payment before doing anything. I gave my credit card number and signed their form (a big error). They took profit to charge me an extra 2 hours. A complaint to my credit card company did nothing. They provided to the credit card company a fake receipt with my imitated signature; unfortunately I could not prove it was fake. Don't use this company, of if you do, pay by cask and only at the end (but they won't probably accept).
