Gateway

I’ve tried to use the chat function but it just turns purple and nothing else happens…

for days I have been experiencing lag moments and all together no WiFi. I’ve restarted the gateway and tested my speeds and I’m getting 0 to 20% what I’m paying for I’m getting frustrated because I can’t find any help line and the only thing it tells me to do is try chatting with one of our experts but the chat doesn’t work. Just need a little help so I can fix this problem before I end up switching companies all together.
