Their customer support is really really bad. Can't say I ever experienced such a bad service from a tech company (I work in tech by the way). They take forever to answer a basic question and then move you from one team to another without passing on the information. All in all, I upgraded to a paid plan and couldn't access any of the paid-for features, and when I asked them about it, I had the following (very poor) answers: 1) it's because you're based in Spain (not true, the features are accessible in Spain as clearly stated everywhere on their website) so then they came up with 2) you have an upgraded plan but your account is basic so that's why it doesn't work (which made no sense, why would the plan be upgraded and not the account) and then 3) oh yes it's because we made a mistake do you want to upgrade to a new plan ? => NO I just want to have access to the features I'm paying for ! This took 1 week of back and forth by the way because they were always "very busy at the moment so please allow 30 minutes before an answer" which usually came hours after.
