Have not received any response from this company!

I was browsing through the internet on Friday the 15 January for a new cell phone (upgrade)<br> I came across a web site called PHONE FINDER. they contact me on Monday morning the 18th January we I gave them all my personal details including my bank account for the debit order.<br> <br> Today is Wednesday the 20th January I have not heard any thing further from them whether the contact has been approved or declined. On there website there is no contact details for them just a email address that I have sent them several emails to contact me urgently I have provided them with a number . I must honestly say that I am very stressed as no one has come back to me. <br> <br> I'm really worried about my bank account!!<br> <br> Sandra
