Debt collector.  The number one collector for Ebay or Paypal debts.
They call, you answer, it's a recorded message that says, "Please hold for the next representative."  And then you wait for a minute or two.  YOU hold.  When they are the ones that called you to collect a debt.

I owed the money to Ebay.  They made a payment arrangement to debit my card $ 25 a week for 5 weeks to pay it off.  They kept their end of the bargain and didn't charge me anything extra.  Even sent a receipt in the mail when it was paid off.

I didn't have a bad experience with them but it was a debt that I owed.  It's a silly system to hold for them, but it worked out in the end.

Just called my cell. Didn't answer. This is happening with a lot of different unknown callers lately. I owe absolutely nothing. I just keep blocking the numbers. A big bad flaw in the Do Not Call thing.

This number has called me almost a dozen times since last week.  I never answer, they never leave a message.  I've already blocked 3 other ICS numbers, here goes #4...

This number calls me day and night. Doesn't lave a message, getting very annoying!!!!!

I believe it may have started when I started using aliexpress.com
