I keep getting calls from this number and when I answer they just hang up

Red Energy. Wont stop calling even blocked number, very annoying. All of the above comments, fit my experiences regarding their calls. Just stop already !!

I keep getting calls from them. Nuisance!

I answered the call and it went straight to "hold music". They then hung up after about 5 seconds

They called me at least once for last 7 days. First time did not leave a msg on my voicemail and second time tonight , the call went to music then hung up.

God they just wont stop calling!
I blocked their number and I have had 5 missed calls from them in the last 2 days

They called twice today. First time did not leave a msg on my voicemail and second time tonight , the call went to music then hung up.
