Harassment of a non-Client

Harassment. I have never had any dealings with Bayport, I have never taken a loan or line of credit from any financial institution whatsoever, but I started receiving regular calls from Bayport looking for somebody else who either provided Bayport a **** phone number or abandoned their number before Vodacom recycled it and I got it. The first 10 times or so I explained that they had the wrong number and I had never met nor heard of the person they were looking for, and asked them repeatedly to remove my number from their system. The calls continued, so I blocked Bayport using Truecaller which has logged 99+ missed calls from Bayport. I received 3 just during the writing of this complaint. If this harassment does not stop, I will bring legal action for harassment and unsolicited contact.
