Anybody Had Bad Experiance With VT6 Support

Iv herd a few good things about VT6 on here so I thought id give them a try but so far I'm not very impressed! Their support takes days to respond and when they do eventually respond its not with any sort of meaningful answer half the time. I'm on their extreme account. Iv had better support from shared hosting costing less than half as much!

I have a couple of questions about how cpanel is meant to work. I have one main domain on my account and 4 add on domains added on with their own folders. Now are these add on domains supposed to be controlled by the main cpanel account page? because I was having trouble deleting files with the file manager. It was saying that I had deleted the files but when i accessed the account via ftp they were all still their and had not been deleted. And what was showing in ftp was what you could access with the web browser. I then discovered that I could log in to each sub domain in cpanel as if it was on it own separate account. So i have a completely different cpanal control page for each addon domain surly this cannot be correct? I was able to delete the files I was trying to delete by logging into that particular domain names own cpanal like so
[url]

I can do this with each of my addon domains is this correct?

Also is their anyway to edit the php.ini file in cpanel? I simply need to make the session save path writable.
