got several calls from this number, no specification as to who it is or what its regarding.

Have been receiving many calls from this number over the last two weeks. It comes up unavailable, but after about 100 calls they decided to leave me a message. I was told to call back 1-800-533-0321, but they left no information as to who it is. Guessing it is a scam

Frequently leaves a voicemail message that consists of a few seconds of nothing, then a hang-up.  Occassionally, a recorded message will say that I need to call back during office hours.  I called back one time and they said they were with Bank of America and that they had several different options for me to pursue as far as paying the debt off of my credit card.  I just said I wasn't comfortable working out my issues on accounts over the phone and they gave me a callback number.  I've never called them back but I receive about 5 calls from them daily.

The phone number 1 -800 -533-0321 is a scam phone number. I got so many calls from this number that one afternoon earlier in the week I decided to call the number to see who it was and try to stop them. Well as it turns out it was man. Young probably in his late twentys or early thirties. He answered the phone sounding kind of bored and only gave his first name. He was very rude and kind of immature. No company name or anything was revealed. I asked him why he kept calling and he preceded to tell me I had accrued a large amount of money on my BofA credit card!(The card was never activated) I had a credit card account with them a while back but never used the new one they sent me.The balance on the old one had long been paid off. He kept arguing with me when I said it was not activated. I got the new card a year ago and he said I had racked up all these charges and balance transfers since April of 2009. He then preceded to tell me or should I say demand that I go get the checkbook so he could get the ACCOUNT NUMBER.He wanted me to pay over the phone. At that point I said I'm not giving you any personal information like that over the phone. He GOT MAD AND STARTING YELLING AT ME! I asked for a mailing address so I could mail it to him and he would not give it to me.When I asked why not he said the check would go to Delaware. I said what is in Delware? HE SAID CARD SERVICES! He did not want it to go there.And that is where it was supposed to go! We went on and on with this. I finally asked if I could pay online and he said no. He again asked for that account number and again I said no.He decided to post a refusal to pay. But he never said anything about suing me or anything like that if he did not get the money. He just said he would call back in a couple of days and collect the money.(He didn't) Most legitimate businesses would threaten you with a lawsuit to get their money. He finally gave up and said I needed to get the statement and send it to the address on the envelope. This guy sounded like he was going to have an emotional breakdown if I did not send it to him. This is a dire warning folks. If you are getting calls from this number do not give your personal information over the phone. This is a scam artist! He has not called me back since the incident and this was four days ago.
