Terrible network!

Over the last few months, my internet has been dropping for 2-5 minute intervals throughout the day. I called and spoke to a rain representative who conducted a troubleshooting test and could not find the issue on their side. They told me they would send a technician to check my router out but no one has come. I called again and was told the same thing and still nothing. I tried canceling but the cancel button online does not seem to work. I have called Rain several times complaining about my network dropping and every time I am given empty promises! My premiums just increased but the service I am receiving is terrible. what am I paying for?!!!!!
