More spam calls

On a free trial, you will literally get more spam calls. Horrible. No good.

Was going to renew but..

I had to cancel a couple months ago because my financial situation was getting pretty tight and I couldn't afford the $5.99/mo for this service. I come back to renew because the spam calls are ramping up again and my budget opened up to where I could afford it again and now the lowest subscription available for me is $10.99/mo. Um? No. I had to quit at $5.99 due to hard times. And now that I can afford that 5.99 tag it's telling me it's increased? Hell no. I'll just block numbers when they call. I don't care if they're being spoofed or not. I don't ever answer my phone anyway and I only know like 2 people. Bring your rates back down or keep losing customers. Everyone is struggling in this terrible economy. Being greedy isn't going to make people want your service.

Quality has gone downwards

This use to be a great app when it came out. Now iPhones basically automatically screen your calls. The price was 5.99. Now it’s jumping to 10.99. That’s just greed. I’ll be canceling and moving onto a new spam blocker.
