They just  called.  said they wanted to give me a lower interest rate on my visa,& need the info off it.

I took a call for my wife and the caller, David Roy (heavy Indian accent)(Manitoba area code - but) and he tried to engage me, insisting he would reduce our Visa interest to 6%.  To make a long story short, after many questions from me that he never answered  I ended up talking to his supervisor Brad Martin(also Indian accent) by which time I had accessed this site (consumer credit advocate - user feedback). I started reading the responses (didn't let him interrupt) and asked if he would like me to read him several more.  Of course he said no and that shut him up and he hung up.
I suspect they are actually calling from India but it doesn't matter.  I still don't know exactly what their scam is but that doesn't matter either!  Try the above for a giggle or just hang up on them

I have checked this out with visa and mastercard and have been advised to not give info to this firm . Stong odour of fish!!!

Here is the so-called scammer's website

we should do something to overload their servers.

we received a call from this number. PLEASE NEVER EVER deal with them or discuss any issues.

Same East Indian accent, provided and number and a website when I asked questions.  d onot give info.  When I asked them to provide me with my personal info for confirmation they hung up on me.  Call your credit card company and ask for a new card RIGHT AWAY!
