Aabaco Small Business Site is consistantly locking up and no help is available. India? Internet

Good evening.  I had and used a yahoo merchant solution site for over ten years.  During that time the site worked well and when ever I had an issue help was easy to come by. 

Recently yahoo appears to have been purchased by Aabaco (of unknown origin) and then was supposed to be changed to Luma *** something.  But apparently that change never did happen.  Since I had been so pleased with yahoo I decided to try Aabaco thinking they would be as reliable as Yahoo Merchant Solutions.  So I signed up for a store site, picked my business name and got started making my new store site.  From the very first day the system crashed several times while I was entering data. 

Each crash would lock me out of the site for over two hours.  I finally found a phone number for Aabaco and the person who was almost impossible to understand tried very hard to be helpful.  He/she finally determined that the problem was on my end as I was using Firefox as my browser.  So, I changed browsers but it was not better.  I have been entering the items into my store format for the past 4 weeks.  I get one hour of work done and then just sit here for two hours waiting for the darned site to reset itself or whatever it needs to do to come back into production.

I feel that I made a horrible mistake trusting this company.  I am way too far into the process of store building to just back out and try to find someone else to host my site.  Never in my adult life have I met with such poor communication and poor reliability as I have found with Aabaco.  If there is ever a class action suit I would gladly join.

So,now I am still locked out after three hours...it appears that once again I will not be able to get a darned thing done.
