One thing I have learned through the years is to stay away from bad companies. That is companies that treat you unfair or badly or is just simple bad at what they do.
Some times this is not possible like with bank or post as there is no better option. But when it is - run. Never use them again.
One company I have left and newer will use again i Kayako. Kayako supply Kayako help desk.
Issue is that I had purchase life time free upgrade.
I will shorten the story of hours of mails and contacts to this: it was all lie. Kayako found a way out of keeping their promise. I see it as a Kayako fraud, nothing less.
I did not get the free upgrade.
This surely show that a company starting with ethics and a great service get destroyed by making money. Customers are not worth anything anymore.
Greed replace ethics.
To help all others not get into problem with Kayako I give this free advice based on 40 years as a international business man:
Do never make any kind of business with Kayako. Save your selves the trouble of purchase expensive, invest a lot of staff time and company money at the risk of have to leave Kayako anyway when you get so badly treatment that you simply must.
