This might be the best ever cloud service in the world but their customer service & billing practices are horrible. I joined this service on April 19th, 2016 through a voucher I received from KASPERSKY for a FREE 100GB of cloud storage, expiration date of the voucher is August 2016. upon registering my account, my credit card on file was billed 100 Euro on the same day, although it was stated on the site that my credit card will not be charged. I have communicated my issue to their customer service through email, I submitted a copy of the voucher as well as the activation code, yet they failed to resolve my issue. then on April 26th they charged my credit card again for the same transaction. They have no phone number listed on the site for escalation, no one to talk to, they are hiding in the cloud filing their bank account with money that they wrongfully collecting. So, think twice before you volunteer your credit card information on their site.
