I have reported this number before.Now they are calling me every fifteen minutes. This is a clear invasion of my privacy. It makes no sense to call let it ring twice and hang up. What does this accomplish?

Showing up on my Tmobile bill texting several times per day. No idea what this is ... not showing on phone.

annoying harrasment

High volume outbound callers such as surveyors, debt collectors, politicians, telemarketers, etc. all try to maximize their resources. Given the general unpredictability of answers, callers resort to using multiple lines per agent employing dialing strategies known as predictive dialing and power dialing. Predictive dialing utilizes a pacing algorithm that factors agent availability, average call times, and answer rates in an attempt to maximize agent talk time with the lowest possible abandonment rate. Despite clever pacing, agents are inevitably unavailable for all answers and abandonment occurs. Power dialing maximizes agent talk time by continuously dialing all available lines. This results in astronomical abandonment rates.

Keeps calling and will not say anything when I say hello.

I won't answer it
