I would have thought if there was a transfer of undertakings the new owners would have to honour orders. If it went into receivership however you would just be an unsecured creditor along with everyone else - customers and suppliers alike. As you are obviously already aware only credit cards give you the protection on purchases over £100 so you're not covered there. You need to find out the current legal status of the company. What a bummer!
You are only covered if you use a credit card i think and then only for a bit.
I lost quite a bit with bloody Dibor like this.
What enraged me is that they then started trading again,and wouldn't honour the payment.
They still send me fecking catalogues!!!
