Thank you everyone for your advice, we are going to safely ignore it for now, and if another letter drops on the mat which has clear proof then we will go down the SAR route but gut feeling it's probably an old orange mobile debt which would have been years ago

Thank you for your advice twoman. Do I not need to send them a CCA rather than a SAR as I thought an SAR was for the original creditor (the company they bought the debt from) or do Aroow still have to comply to a SAR

Hi, So the other half received an initial letter from Arrow Global today saying that they are trying to contact him about a personal matter aka trying to recover a debt. After reading other posts myself and the OH are in two minds whether to ring them as most have said to deal with them in writing. However without phoning them we can not access how much debt they are trying to collect and from what company they are collecting on behalf for. Any help on this would be great!
