Good old Snap on (or sun, a totally different company, as my Snap on dealer keeps telling me even though it says Snap on on the machine and he arranged the sale).
I bought one of thier new DGA2500 gas analysers in July 2007, had the engineer out countless times to fix an intermittent fault which " could'nt be happening " although all there adverts show the machine doing what I was complaining about!!!! Various engineers came out changing the same parts and telling me they were faulty (EVEN THOUGH FITTED LESS THAN A WEEK BEFORE). Eventually I got fed up with the amount of MoTs I was cancelling and had to threaten legal action to be given a replacement machine which was delivered in January 2008. The cancelled MoT tests cost me a fortune.

Bought the machine on a two year deal which included all cals and updates. I Kept receiving bills for cals etc and kept phoning them explaining the deal until recently when they refused point blank to carry out cals due to unpaid invoices. Fine I said lets wait until I cannot test and I will charge you £45 per hour until we get to court and sort this out once and for all. After various phone calls and a meeting between staff I was credited for all the outstanding invoices but not even an attempt at an apology.

I recently changed banks and the new bank transfered all my direct debits over. I received a phone call from Snap on finance to tell me that my direct debit had been cancelled and I needed to fill out a new form and send them a cheque which I did on receipt of the form.
On 5th February I received a call from them saying they had received the cheque but no form even though they were sent in the same envelope. They told me I must fill out another form and send another cheque or pay default charges. On friday 6th February while I was at the bank sorting out why my d/d had not been set up Snap on finance phoned to say that the account number I had put on the form they didn't receive was incorrect!
While at the bank I was given paperwork showing that the d/d hed been set up and acknowledged by Sanp on finance on 5th December but THEY had cancelled it on 12th December.
I received the new form today.
I will NEVER buy from them again. Beware all those that consider buying from the great Snap on.

Regarding Joe at Celtec - great man served me well in the past.
