Don't be too hasty.
All I can offer is advice on the technical issue not necessarily the different products.
I often find this issue logged as a fault with the services i am involved in. More often than not, it is actually not the website or the product itself. It can sometimes be the actual set up or browser of the individual concerned.
Each and every person uses technology in different ways and has different settings within that technology. If the issue does reside at the website end they will invariably see many people with the same problem and fix it.
However, if the issue is at the user end then that is something they will have no control or influence on. Therefore, they might appear unhelpful but they may reasonably be suggesting its something they can fix for legitimate reasons.
The hard part is judging where that line is in between.
My advice to you would be to eliminate the workstation you are using. Use another, completely different, pc or laptop to log in. If you still get the same problems, mention it the support team. They will believe you more if you help them to understand it further.
Either way, they should be a little more helpful than you have suggested. They have a user unable to use their product. Tell them you might leave, that might make them take notice!
