Jane, I am sure there is an issue here over the transfer between Citibank and PSPC No1 Ltd. If I understand it correctly the transfer between the two companies was not completed in such a way that gave PSPC No 1 ownership of the "debt". You need specialist help. Contact NAMV before you do anything, as they may put you in touch with Ahmad Butt who has experience in these cases.(posted 7598 days ago)Tell your ex not to acknowelege the debt at this stage.
A Statutory Demand is the first step towards bankruptcy. You have 18 days in which to set it aside, usually used as a threat, but always has to be taken seriously.
NAMV can be contacted on 01889 507394
Hope this helps Jane
