Customer Service Recommendation


Just a quickie to thank you for all your help and advice in the initial stages of this below case, over a year ago... I was so despondent initially, but you invited me to call, talked me through the necessary steps and recommended the transferring of it to the High Court etc
I have today received notification that they finally tracked her down and that her dad finally paid the debt which has now been transferred into my account, so all's well that ends well.
Many many thanks once again to yourself and your team and I will certainly recommend you to anyone I know who needs similar help.
