cc: OFT,
I have no idea who you are, let alone what you expect me to "make a payment" for. You obviously have my email address, so if there is a "personal matter" that you need to contact me urgently about, you know how to do so. I do not make a habit of calling up people or businesses who don't talk to me but instead want me to talk to them.
If you imagine for some reason that I owe you money, please state what it is you imagine I owe and why you imagine I owe it. If you are simply soliciting for charitable donations, please cease correspondence with me.
I have included in this response, by email carbon-copy, the Office of Fair Trading.
Sincerely,
Mr Kay
