Are former Alltel customers considered second class?

I guess former Alltel customers, that were converted to Verizon are considered second class customers. I just got off the phone with Verizon customer service. The reason for the call is that I have been receiving obnoxious calls that I want to block.I am on the Do Not Call Registry but no one seems to pay attention to it. So, in going to that (block number) function in My Verizon, it says I am ineligible for that service.

So the call to Verizon. Verizon customer service tells me that since I did not have that feature enabled when I was with Alltel it is now not possible for them to add it to my account.

They said that I would have to get a new account and new phone number (which would totally change my plan and pricing). That is an absolute non starter and sounds like a bunch of horse manure to me. I am currently finished with my latest two year contract and am on month to month.

I spoke with two different reps about this and the last one who commiserated and said she wished she could fix the problem but couldn't and at least suggested that I talk to a manager, but I had no time left to do so at that time.

Anyone have any thing like this happen?

Any advice or suggestions appreciated.

Thanks
