I too have been called by these annoying PPI claims people, listing a london phone number. NOTE They are calling from Durban in South Africa and are not UK based or registered with Ministry of Justice MOJ so they are acting illegally in the UK. Note there is a UK based company with the same name that ironically sells PPI, but appears not to be connected to the Durban one. First Call Centre Sloutions, 220 Flanders Drive, 4300 Mt Edgecombe, Durban South Africa 4302. Enterprise # 2009/12406023 Phone: +27 31000000 (Not sure if this is a valid number) Complaints +27 722794 893 ( I think this is a mobile number) They had an advert in Durban papers last year for call centre staff for a UK Campaigns giving contact number of Pranesh or Deon Vismer on 0722794893 Doen Vismer has a page on Linkedin Hope this info is helpfull.
