The worst that can happen is that you sign up with a absolutely rubbish company and you nightmare begins.
Even good customer services won't make up for the loss in frequent downtime, slow access times or restricted file sizes.
Not to mention the loss in revenue from your business un-need frustrations and anxiety defiantly starts to out
way the attractive cheapness which initially enticed you in the first place!
All this said but most companies do offer the contract on a free trial basis, so that sound like a wise option to take.
