Axxess is a *******

I have had little to no network for 5 days now. I called them twice and was told to reset and reboot my router. Been trying to get through to their call centre for 2 days I can’t get through. I’ve had to buy data with another network because I work from home and need network. All this while having paid axxess their full amount. I am sick and tired of them I just want to cancel my account with them.
