Way too frequent outages due to “Network Performance Issues”

For the last few months, we have experienced frequent outages due to network performance issues. No heads up or warning just happens. My fiancé works from home full time and must remain connected and she has to clock in and out. These outages have greatly impacted her ability to work. She has missed days without pay due to these outages. It is really frustrating to pay this much for a service that works this poorly. Already not getting the speeds we pay for and can’t even count on the service to work.
