I have the same problem, I have just called GM Connect on 01254 693392 email info@gmgroupltd.org or b2b@gmgroupltd.org Address is G.M Group Sales and Marketing ltd Suite 310 Daisyfield Business Centre, Appleby Street, Blackburn Lancs BB13BL.
www.gmconnect.co.ukI have given my mobile number and told them if I get anymore calls from their company I will bombard them with calls and direct spam to their emails. The lady tried to put me through to customer service which was great because it means the number I rang 01254 693392 was not the nunmber where they wanted calls! so I will let you know how I get on, but suggest you do the same!! I have also seen that if you register your phone on TPS then this should not happen, but it was more fun venting my frustration at these 4-5 calls a day.
Good Luck..
