Hello MasterD,
Firstly I wish you had contacted me first over this and I would have advised against you paying the said Company in this Manner. Sadly You didnt know me then.
OK Lecture over, Have you got written documentation of the offer and Transaction? Yes, Good stuff yes write to DCA and send them the proof of said transaction etc. I also advise you get legal advice in UK, 2 methods CAB's (Citizen's Advice Bureau) Malaysia has a similar Dept up Jalan Tun Perak I believe in UK they are probably not up on this sort of Prob but try anyhow. you can also get a specialist Legal Advisor to help you in this prob. It may be worth the cost plus you may get legal aid support (Basically Costs Paid) depending on your circumstances. On top of that I have a Contact Number for a Hi Power legal firm in KL and Can send on if you want, apologies if it takes time as On Hols at the mo but it P@@@@s me off to hear your story.
Hope that will help you.
