More bad news from India....
Dear Mr Farrell
I am sorry for the earlier response sent to you.
Currently, there are payment issues with the UK debit cards, which are likely to take a few days to resolve. The Payment made by credit cards is being accepted but payment by UK debit is not possible.
I hope this is the information you require.

Basically I got a very poor response parroting what I had already told them, proving that they didn't pay much attetion to my complaint. Basically they still haven't worked out how to accept UK Debit card payments yet. It's over a week now. Final 3 Greens might have a point!
