How many people are still doing Cold Calls??

[Derrick Gordon]

I have been having an extremely frustrating time with my phone numbers, about 85% of them are disconnected or wrong numbers. This is just killing my workers time and my efficiency. What are the premiere Skip tracing services other than TLO? Which one's should I avoid or are they all going to yield the same frustrating results?? Currently using REI Skip and the results are frustrating at best.
