What happens if I add for eg 2 days of repair time for 30 days after I already have 18hrs repair time for 30 days? Will that 18 hrs package be useless or do they add up? Thanks
Your existing add-on expires at the designated time (when it has always been due to expire) and the new extra will expire in 30 days. For a time you get the 18h+48h or whatever extra you use.
