First check if money was refunded.

If not, contact support:

I have contacted them just wanted to know if this was a known issue
and know i wasn't refunded for all that i know

Not that I know about it. I didn't have any issues with my Master Card. Do you have some kind of net baking to be sure it wasn't?
It may take up to 48h for support to respond, but if it wasn't refunded, I'm sure they'll take care of it.

give me your details and i will try and see if it works

I think I've read about some mixups as a result of certain US banks blacklisting GOG for having been incorporated in Cyprus or such. You should probably wait for support and keep checking whether you've been refunded by your bank to see exactly what's going on. I've personally never had problems with payments here at all.
