Server keeps freezing like elsa

They aren't bad, but I have some issues. For example, the server sometime would freeze for no reason. This has been noticed on several demos and a few live accounts servers. Now, I have reported these and at times I had to open new other accounts on different servers. This must be addressed very urgently, I can't keep opening new accounts. Especially because this broker has a limited amount of how many accounts I can open. Getting through to the live chat helpdesk is a real pain because one has to often wait a long, long time in the queue. Other than that everything is peachy and I actually really like their spreads.
