I answered- they had my nickname down and started saying they are calling on behalf of something but then the call disconnected. They call me like 6 times a week so I finally answered and it just spam.

Woman was speaking to someone when I picked up the phone. Our conversation:Hello? HelloHello?! Hello!I'm quiet for about 10 seconds. She says nothing. I hung up. Won't answer again. Phone said unknown name.

Claimed to be a charity! Block

Calls started yesterday. Phone says scam likely - no name associated with the call. A message is never left. Blocked the number.

I've been called by this number many times, always at or just around the same time of day. It's definitely a spam call.

I have been getting calls from this number for weeks, and sometimes twice a day, among the other 10-20 calls I receive weekly. It's a nuisance to say the least. What do they accomplish by doing this? Does an answering service equal answering the call?CherylIllinois

Left a voicemail with no audio

Kept trying to get me to sign up for sponsorship deals that were not available on the actual Sierra website and was very persistent so it screamed scam.

scam call alert

We have never answered the many calls from this number, as the number is tagged as scam, not trustworthy, etc. Shows up on my caller ID as Sierra Club. It is not! They have never left a message.

I have been called every day for the past 2 weeks. No one on the other end.

Every day, several times often, I get a call from this number with only one ring. Caller ID says Sierra Club. This is very annoying. I am a Sierra Club member and if it is indeed the Sierra Club, will terminate my membership.

Person tried to have me use my credit card to donate money to help save with the climate change and other problems with the economy that's going on. Was asking for $400 dollars. The person said that the phone call was being recorded for their file purposes

Repeated calls

They keep trying to call me. I never answer and they never leave a message because I have spam blocker app.

No VM left, didn't show in my call log, wasn't blocked either. Super strange.

CID say Sierra Club,,,5103064001. Revived ‘renewal’ notices,,,,, I make a donation when I can, not a reoccurring pledge. Retired, failing health, do not give over phone. With 138 days as of today, have revived 168 pleas for donations via U S mail. A millionaire could not maintain the pace. At least 4 from Sierra club, last in 05/08, to renew membership. I don’t join, but used by so many to plea for donations! Wish I had it to give.

calls EVERY week sometimes twice a week, never leaves a message. Always calls early in the morning.

I already had them on block and call still went through. I *67 them and listened to their recording stating they were a nonprofit organization, covering several things and nonprofit calls can't be blocked...? And also at some point I had interaction with them. I'm pretty careful and private, so I'm not sure. The lady on the other end did state she was with the Sierra Club.

I called it back and the woman who answered said she never called my number and that she had no outgoing record of her phone dialing me. Repeated calls from this number received all labeled as 'Sierra Club'.

Constant harassment. Receiving multiple calls per day that I do not pick up.

only one ring - no message

This number has come up on my blocked caller list at least 25 times.
