Called the number back and talked to a lady. She put me on hold and next thing I know the blocked call phoned back on the other line saying he was with Riverside Assets. He wanted my name and I told him he was a scammer.
Receiving same type of calls, very stern when I've tried to call back they tell me that my phone number has been blocked to receive calls. They call at work, home, cell and now family/friends. They want me home on a specific day/time to deliver legal documents. I don't think so .....calls at work are monitored and embarrassing to explain. Must be they don't have much business as I'm called at least 3 times a day!
Returned the call after an automated voice left a message directed at me with a bunch of numbers. This company is trying to collect/settle on a debt on behalf of a credit card (in my case). I did in fact have a judgement against me for this debt, but it was part of my bankruptcy; looks like they're called in by creditors who are still trying to get money, even after 5+ years.
