I have been contesting a more than 7 year old mobile phone debt which Lowell Solicitors brought against me. They harassed me for months and would not accept that the debt was statute barred, but also couldn't provide any evidence to support their claim, saying that this was not available/not necessary. A court claim followed, which I defended (with thanks to inspiration from reading other peoples similar experiences on this forum) and today I was delighted to receive the confirmation below that the claim has been discontinued.
For anyone else in the same situation I hope this gives you some encouragement to keep going and stand your ground. They're entire business seems to be in buying old debts which they know cannot be recovered, but they harass and intimidate people until they pay up.
