Anyone had any success with Buyacar.co.uk

Hi
I ordered a new car from Buyacar back in June. The usual 8 - 10 weeks went out through the window and I am now expecting to take delivery on Monday 17th.
My intention is to purchase my vehicle by CC which the company are more than aware of. (0% don't fret)
My problem is that no matter how many times I have asked the company, Even talking to the operations guy [TEXT DELETED BY FORUM TEAM] they have yet to take the outstanding balance. I have emailed them, even threatened to cancel my order but still no positive response other than a callback last Friday saying it will be ok to pay by CC he will get back to me by last Saturday. Another no call.
Has anyone any experience of this company good or bad???
