Unprofessional, poor customer service

I received three phone calls in the span of 2 minutes while at work. On the third attempt, I answered the phone. After kindly informing the agent that I did not have the time to take these calls, nor was I interested in hearing about other premiums, I was met with a very unprofessional response. The agent questioned why I was not interested and once I calmly informed them that I did not have the time to deal with this call she abruptly ended the call.

I expect a kind approach to customer service processes, especially when the customer deals so kindly with the agent. Please take some time to properly train your call agents in the proper way to treat customers, and if I haven't picked up a call do not bombard me with multiple calls.

Unprofessional.
