No they should not ring.(posted 7581 days ago)Regardless of whether your friends allegedly owe money or not, they should not ring.
What your friends should do is the following:
1. Accept that mortgage lenders, mortgage insurers and brokers, through mistakes, mis-selling, or dishonesty, can put your friends into a position where there is an *alleged* debt.
2. Prepare to deal with the consequences of that. Which they should do by reading the Do's and Don'ts section of this site.
Absolutely do not return calls of this nature. Read the site and note the other methods used to establish contact and do not succumb to them.
Good luck.
