Rewardsco remove my number

I just received a call from ***, they are looking for someone I used to stay with which I no longer stay with.

I politely gave the agent the number of the lady they were looking for and asked her to remove my number. She says it is not possible. she can not do that. She then drops the call.

With years of call center experience, I do not appreciate being made a fool.

tried calling the company to request that my number be removed, No Joy.
