D&L are Direct and Legal, a well known debt agency who will not stop calling despite what they say. The call centre staff do NOT have the option to remove your number just like that no mater what you say
I've gone through this with them several times, the calls only stopped when I sent them a letter regarding telephone hasslement using template letter found on
www.consumeractiongroup.com then in forum rooms.
Incidentaly it didn't stop the letters chasing for money owed.
If it is Direct & Legal Collections then call them on 01280 707930
as its cheaper than the 0870 number
