I'm not sure if others have had similar problems but in regards to customer support, I'm struggling with the KVS tool right now.

I made the mistake of signing up for a year membership rather than a monthly one and after testing the tool once I didn't find much use for it. I thought I was in the trial period but after emailing their customer support to cancel, they are now refusing to refund me my membership fee. I even asked that they only refund the difference between the yearly fee I paid and a 1 month fee (despite only using the tool once) and they still said they wouldn't. I realize it was my fault to selecting the year subscription but for a young company, I'm shocked they would try to milk a full year fee after one week. Buyer beware if you sign up for the KVS tool.
