Can I call UPS and say that a driver called me to come to my house, when he has no right to do so?

You're not obligated to answer the driver's questions and concerns.

Tell the company that given they're handling your claim, all communications must take place with them, and not the carrier. It's the company's responsibility to address Issues with the carrier, not yours.

It's that simple.

too late, I solved the claim with ups and the delivery man, this will serve as a lesson for a future SE. However, I still want a refund, so what are my last options left?
