Received a couple of robo-messages in my voicemail with the following message:
"Good evening.  This is Adam from Onprocess Technologies on behalf of Asurion.  This message is for the owner of wireless number xxx-xxx-xxxx in regards to claim # xxxxxxxx.  We are calling in reference to the replacement equipment that was delivered to you on April 30th.  Asurion still shows there is non-working equipment that needs to be returned.  I would like to remind you that all non-working equipment needs to be returned in the postage pre-paid envelope that was provided for you as soon as possible or you may be charged a non-return fee of $300 for the cost of the replacement equipment.   Please call if you have any questions at 1-800-762-0276 and when calling, please reference your wireless number xxx-xxx-xxxx."

The thing is that I did not contact anyone to get my phone replaced and I called Asurion who told me that they do not have any record of this.

This is Asurion, the company who fulfills cell phone warranty replacements.

they identified themselves as Assurion and it was the cell phone insurance on my husband's phone, reminding him that he hadn't returned the bad unit yet.

Same thing happened to me.  Someone ordered a replacement phone under my phone number but its fraud and Asurion has it as fraud.  So I don't have to pay and the scammers phone got deactivated :)

I THINK IT IS ASSURION INSURANCE CELL PHONE REPLACEMENT.

April 25, 2013.  I received the recording from this number. I called Asurion 800-922-0204. They told me there is an investigation and that this is a scam phone number NOT Asurion.  A claim WAS filed by the scam artist, but the claim will be removed from my account.

Probably Asurion, I just returned a phone to them..

It is Asurion calling to remind you to return the broken phone...

Received a call from this number, answered the phone and there was no answer on the other line...pretty strange.

It must be a scam. Don't respond.

I got one call mentioning my mobile number, no name, and saying that I had received replacement equipment in September, and needed to return the defective equipment in the pre-paid mailer I received, or be liable to pay $300-$350. The message was a recorded, robo-voice.
