Gigablast instability and the suggested solution

I upgraded to gigablast recently and have constant instability issues ever since.  It will work great and then randomly I will lose all internet, then a few minutes later it will work again.  Once was during a webex with a group of potential clients and potentially cost me a lot of future business based on my normal conversion rate.  

I had the preferred 150 before and it was very stable, but I needed faster upload speeds. 

So after a few rounds of techs online and a few sent out to my house, I was basically told that the gigablast has had instability issues since everyone started working form home and my best bet would be to downgrade to the ultimate 500.  For the same cost I am paying for gigablast.  So, we are unable to deliver you a consistent quality product, so we want you to accept a lesser product but pay us the same amount per month.  I was told it was because I was on a promo for gigablast.  What about a promo for costing me thousands in business and not being able to deliver? 

Nope, you are stuck with us so you will pay what we say regardless of the quality of product we can deliver to you.  Either fix your issues or compensate your customers until you can fix your problems.  Don't stick your customers with lesser product and overcharge them because you can't seem to figure out how to fix the network.
