Do you guys think this could be a trick performed by the reader so I can't leave negative feedback?
If that is what you really feel then you should not have continued to call back and waste your money on someone who is not a real psychic.
A reputable reader would not resort to tricks for basically pennies. Reconnecting and recentering themself every three minutes is not worth it for a real psychic. I can see a real psychic doing it if a system is having issues, but it really isn't worth anyone's time and energy to do that for a few dollars.
With all the good feedback, why do you think they would bother to do this?
