Smartswitch poor customer service

I am living in a rural area. At first everything went fine. Then in October 2019 I started to get problems with internet speed and availability. Long story short: since then I have tried to sort things out. Upgraded etc etc. Customer service is poor. Sometimes you do not get answer on the phone. They do not phone back as promised if the person you want to speak with is not available. They do not follow up after they said they will. There is always a "reason", but nothing is done to get the problem solved permanently. Maybe they must just say that cannot provide the service, but now after 7 months my internet today is 0.08 mbps!!!
