RingCentral: Getting Very Little

We have ten digital lines and not one of them works regularly.  So sad about that.  We have spent thousands of dollars on this service and still don't have phone lines that I can send and receive phone calls over.  The Customer Service assistance is kind but takes so much time out of my day and I have to call them on my cell phone because they can't hear me using our Ring Central phone lines.  Something a bit ironic about that.  Been struggling for at least six months with this system and because we don't receive or need to make a lot of calls and we all have cell phones we have been living with the troublesome situation but I think for us we just have to cancel this service and say enough is enough.  Spending $200+ per month on a broken phone system is ludicrous. 

With that said, it is possible it might work for you.  All the other reviews are good. It could be in some ways that we don't have a great internet service and have alot of things going on that may require too much bandwidth.  I honestly don't know. But if this were the case, I feel like Ring Central should tell us "This is just not going to work with your system".  Or if it really should work but we haven't been able to make it work for the life of us and I have had so many, many telephone calls with Ring Central Customer Service, then I think someone should come here in person to look at things and fix them once and for all, if it is even possible. 

So sad/mad about this all.
