Inundated with spam calls

I receive spam calls from Absa's credit division countless times a day from different numbers. I did not consent to Absa using my number nor am I a client.

I have told different consultants over the last week that I'm not interested but you keep calling from different numbers.

PLEASE REMOVE MY NUMBER FROM YOUR SYSTEM or I will contact the consumer board. This is *********, desperate an highly annoying.

Please fix this immediately. The endless calls I get per day are annoying
