I quickly answered & hung up so they couldn't leave a voicemail. Luckily I have an iPhone and can easily block calls ;) They won't be calling me again.
Want to perhaps get them steaming mad if you decide to answer the call, be impossible with them. Put them on defense the entire conversation with such responses as what's it to you, what's it to them what credit card you use, your balance, etc.,. Instead of giving out information like they hope, they'll be trying to come up with ways to answer. Their only ways out would be either hanging up or cussing you out. I'd expect it could drive a scammer up the wall.
Not sure what all these calls are about. I am getting a whole lot of spam calls from the 205 and 818 area code. I believe they are all connected. I don't know anyone in this area code. Constant call and hangups from these numbers:
205-368-5965
818-428-1768
818-920-8894
818-527-4140
818-477-4380
Keep it up! I block each one of these pesters. In the case of 818-920-8894, they have a website that promotes orders of Dish Network (although there is a message on the website that reads:"If you have noticed an expiration message on your site, that means your Premium subscription was not able to be renewed. This may be due to a number of reasons, including an expired payment method"
