I have a Panasonic land line phone and I used up all of the memory for blocking numbers, and we still get spam calls. I don't answer our land line anymore, but the telemarketers keep trying.

If someone calls me on my cell phone and doesn't leave a message, I put them on block. I haven't reached the limit on blocking numbers on my cell phone. I suppose I could change our land line to a voice mailbox or cell phone.

Credit card companies and some companies that deal with you require a phone number, but I assume they are the ones selling my information. I even think the cell phone companies and some cell phone companies are involved as well. I think you need a voice mailbox for those you deal with and a private line for work, friends and family.

The Inquirer subscribed my parents and billed them. My parents were too polite to pay after disputing it with them.

The Inquirer tried that with me when I bought my house. I told them they played that game with my parents and I wasn't paying.

Talk to your credit card company and explain you tried to reach out to them and you wish to cancel and they are not responsive. Tell your credit card company that you no longer wish to pay. You have to try.
