I too would give this company a "zero" star rating if it were possible.
They have a "no refund" policy so we lost $700 Cdn...even though they did NOTHING but leave a mess.
They are not available by phone.
They are in the Ukraine and when they leave the office at 6pm their time zone, those of us on EST have a mere few hours to try and track them down.
The email communication lags are days...not hours. When they say, "yes, we can do that...", it actually means "No...we have no idea what we're doing".
They are using an old API system that most carts no longer use.
So...be forewarned...you will end up doing the migration yourself or paying another company to do it many, many weeks after you paid this disingenuous company!!
