Also kept getting calls from Maritz Research several times a week - never answered phone (thank goodness for caller ID) very annoying. Have now gotten calls from the same number but the caller id was "msc-vip6.nj.ipx". Not sure what address this is, but the phone number is the same.
This is a debt collector--pretending to be something else !! Tricky little rascals ! Absolutely a debt collector, possibley Calvary, asset acceptance or Nco but it is a debt collector.
I just received a call from this number from somebody claiming to be from Tmobile conducting a survey on why I discontinued my service, which I hadn't. She quickly told me she was sorry for the mixup, gave me this number 800-937-8987 if I had questions, and hung up. She knew my name.
