Called the number and greeting was "Field Center for Energy (or NRG?) Research Group". They've been calling twice a day (usually in evening) for several days now

this is the second day in a row that i received a call from this number - no message and hangs up when answered

Solicitor - Safe Nest

Have called at least 5 times in the last 2 weeks, I am on the Do Not Call list to begin with, and have requested name be removed. They have burnt cell phone minutes which I demand reimbursment.

Called 4 times in 1 morning, when calling back number is engaged

Keeps calling all times of day and night. does not leave messages. very annoying. I am on the do not call list, so they are violating that. I dont answer unknowns unless it is one of my friends that I know is calling me.

Not sure if its a scam or a phishing phone call but apparently I recieved this call with an automated msg notifying me from an unknown card company that I can lower down my apr to 6.9%. Its the final notice and I need to respond promptly for this offer. I pressed 1 in order to proceed and some person got on phone. But he verified my name and I asked him what credit card company he was representing. not sure why but he hung up on me right then. I cant call back because number shows up invalid. Upon research seems like more than 100s of people are suffering thru same issues.
