Wi-Fi outage promised the credit and didn’t receive

I constantly have Wi-Fi outages. I spent hours on the phone with support multiple days in between my job and they promised to give me a credit for multiple months where I wasn’t able to use my Wi-Fi because it continuously has outages. All I wanted was three months refund and to get six months or a year free Wi-Fi or I’m gonna be forced to change carriers somebody needs to reach out to me and help me with this matter and make things right before I cancel my service.
