Hy i see that hostony has new offerts 200 300 GBs. My question : I have a special pack with 30 GB can it be upgraded to 200 or 300 ? I am paying the same price ?

Hello.
yes, your account can be upgraded to the new plan.
Please submit the trouble ticket to our support department.

Thank you.

I had 20GB and it was automatically changed to 200GB. Might want to check via cPanel how much space you have - they probably just forgot to change yours if you don't have more than 200GB or so.
