I got a missed call on my cell phone from this number today. I didn't know who it was so I decided to search for the number online. After reading some of postings above, I think I figured it out. I bought a new phone from T-Mobile yesterday and I was told that I may be contacted by their office for a customer service survey. It is supposed to be something that they do randomly to ensure that their sales associates are doing their best.
It doesn't matter if you're on the do not call list ... if it's from one of the accounts you own, they're allowed to call and pester you unless you ask to be removed. :(
They probably have predictive dialing. They know it'll take 5 minutes per phone call, so when you're about 4:50 into a phone call, it'll dial the next number. If their phone call runs longer than 5 minutes, you're just sitting there saying "hello hello" and then your number gets put back into the pool and you get called again.
I just got a call from this number. We actually get a call from them about once every few days, so it's nothing new. It seems kind of "phishy," if you ask me.
I recieved a phone call on 8/31 at 8:30pm CST. It was from 801-823-2020. A girl asked for someone but you could not make out who she was asking for. When asked again who she was wanting to talk to she hung up. Today at 8:33pm recieved another call from 801-823-2020. Did not answer this time but decided to do a little research and came up with this blog. Nice to know I am not the only one getting calls from this number. Also, thanks for the "no call list" number. I do own a T-mobil phone; I do not have an accout with Washington Mutual nor do I have an account with Chase.
