Got a call from this number on my cell phone yesterday (4/14/14) in the morning. Did not answer (my standard policy if I don't know who's calling) and they did not leave a message. That # is now blocked on my cell phone.
Got call from this number just now. Started off by saying "this is cardholder services. There are no problems right now-" I hung up. There's currently a scam in my area where if you miss a call and call the number back, they charge a service fee and a bunch of other garbage. Since I'm taking care of issues for my aunt and grand mother I try to answer anything I can, but this may be one of those out of country scams. I'd avoid answering this call or calling it back.
If you received the call on your cell you can block it if its an Iphone. You may be able to do on other cell phones as well. You can always call your cell or phone provider network and have them block this number. Once blocked, you will not receive their call.
In all honesty, don't answer any calls from odd looking numbers or from numbers you do not recognise. If they know you, or if it is important, they will leave you a message. Cheers
