False advertising to get customers to take their calls

I received a call from a 3rd party. The lady advised me that she calling on behalf of King Price. They are doing a promotion. What was said is that if i take the call from King Price and i let the agent take me through a quote i will receive a R600 voucher from Isabella Garcia. Immediately after i dropped the call, King Price called me. My truecaller said its from King Price Insurance ***. I spoke to a guy from King Price but i never took up the offer. I have not received any Voucher or any communication about the Voucher. This was definitely related to King Price as i received the call a few seconds after i dropped the call from the lady that spoke about the voucher. Please be aware of this **** to get customers to take their calls. This is actually false advertising. My calls are recorded and i will escalate this issue.
