Last week I made an online purchase for an item on Bidorbuy. I ensured that I was on a safe site when I enetered c/c detail. Transaction seemed to have been approved. Then I received an email from bidorbuy to say I need tp supply a photo of the front of my credit card; ID; proof of address. I am suspicious of this request. I have checked my statement.....the debit has not yet been processed. Is this a valid request?
