Unbelievable lack of support!
Heybooster could be, in the future, a good product but it's not yet mature and they must learn how to support customers.

While activating I had a problem, sent TWO emails and got no response.
I managed anyway to get access.
After testing it, I can say that reports are too simple.
There is a Display performance bug, too.
It reports: "There is no active display campaign" and that's not true, Google Ads was connected.

Asked again for support, this time Neslihan from heybooster replied this:

"I will check out the issue on my end and help you asap."

8 days are gone. No more reply.
Refund requested.

Please, do not compare it to Databox...
