On going problem with avg

Thank you for your reply to my problem.The tune i had was a hand over my computer to you to fix for the 3rd time my problems I think the ref No was 6361230 with Karthik.The problem of AVG not opening was fixed and i used AVG TUNE and tuned my computer .After a week tune will not open again and is saying 44% tuned ,but will not open to let me use it 
 I now have no apps showing on START  I have no INTERNET EXPLORER (this was the problem last time)
  I can only use GOOGLE CHROME.
I think I should have a refund of my payments to you as you have not solved my problem.I think three attempts is saying to me enough is enough let get rid of AVG
