Worst support ever

I bought a lifetime Tier3, on a start I was satisfied with the product, then one day, after some months... I was no longer able to use it.
Every time I logged into the account I was redirected to purchase the premium version.
I contacted support for a year and a half, always receiving lots of excuses and Felix tell me if i want a support I had to pay for the premium account (every year)... But if i have Tier LIFETIME.. Mr. Felix is ​​rude and a scammer eith this behavior. Be careful.

Unfortunately it was not possible to request a refund and I am no longer able to use the platform.

It is a shame and a lack of professionalism and I hope that Appsumo with its contracts with new partners will include agreements that can protect us.

Worst experience ever! Be wary of Ranktracker and we place negative reviews everywhere to help others not fall into this trap.
