Some time ago I received written correspondence from one of the main Credit Card companies informing me I had been mis-sold a Card Protection Policy. I was asked to sign some documentation and return it to them and I would be refunded within 40 days. About two weeks after sending the signed document I received a letter telling me to send them some documentation e.g my birth certificate as proof of date of birth. I sent my passport believing this to be sufficient. A couple of days later I received another letter stating that my CPP could not be found!!!! Another letter followed insinuating that a passport was not a sufficient form of ID and by the way we have mislaid the copy of your identification that you did send us. Surely a passport is sufficient enough to prove I am who I say I am?
