App good till now

Been using the app for about a year and liked it till recently. The past several weeks the app doesn’t allow me to pickup calls without them going straight to voicemail. Then if I’m on a call using my phone application and someone calls my Tresta number it automatically hangs up the call.

JUNK JUNK JUNK Keep your credit cards in your pockets

So I signed up for their “Free” trial .. checked out what they had to offer and after an Hour of Signing up decided it wasn’t for me and Guess what ? They won’t let you Cancel .. You have to call In to cancel and when i called in it says “No one is available to take your call “ So now am stuck and they want to Raid my credit card after the trial or even before .. Hey Tresta if I signed up ONLINE , Why can’t I CANCEL ONLINE ? crooked way to do business . Gues I am going to give ya guys some prepaid card and replace my card and am DONE . STAY AWAY guys .
it is a LIE they do not have a 24 Hr call center to Cancel .
