Place, "claims group direct" into Google..there are numerous negative comments from others, at the very bottom you will find the MSE forum that states you can return the pack within 14 days for cancellation... or to secure the return of any funds on hold, this I also strongly suggest you do, whilst you have the choice.
Claiming back mis-sold PPI is not rocket science, you can do this yourself for free whilst keeping everything that's returned from the creditor(s) in question.
Basically you initially need to write to the creditor recorded; stating the reason(s) why you consider the PPI was mis sold, requesting the return of your premiums and any added interest. If you cannot resolve this matter within Eight weeks, you are then entitled to ask the FOS below, to look into your complaint and overturn the creditors decision, should the FOS decide to the contrary in your favour.

As for them being regulated by the Ministry of Justice....that's even more scary. Dr Harold Shipman was regulated by the GMC who's primary duty was to protect the public..... look what happened to his customers.!
