NO INTERNET ACCESS

I am beyond disappointed and actually angry with the service I have been getting while using your router. For the past 3 weeks ,your router does not have internet access for bulk of the day. I have reported this countless times and even received a reference number *** ,but to date I am still experiencing this issue. I am having to spend extra daily buying data,yet I have a router that I'm being charged for. If you are not able to resolve this issue, please cancel the router and refund me my money for this month as i am paying for a service I can't use. Also I have reset the router numerous times and obviously that has not worked!!!!
