You have incorrectly aligned my mobile to one of your clients and it is driving me MAD!!!!!!!

Alexander Forbers, some how somewhere you guys have latched on to my mobile number ***; and aligned it to a man called Hardest who lives at 2 Somerset Road. Because I am now on my THIRD courier call, for a delivery from AF to this man and I keep repeating that this is my number and has been my number for 21 YEARS. can someone please for the love of peace - get this man's actual mobile number and remove mine from which ever data base it has been aligned to him on so that i can stop receiving these calls!!!!!
