Harassing owner of a recycled no

I have a recycled vodacom no that used to belong to thier client ms Tracy lee Anthony who hasn't been paying any of her bills - all the other retail companies she owes has took my no off thier system when I explained that the no has been recycled - markhams on thd other hand 3 months later calls me weekly now daily <br> Look on fb - there's only one to Anthony - get better debt collection agents - stop passing the buck - I am not a customer so no matter how much you harras me - your actual defaulting customers still won't get the message -
