Green Wireless solutions - Bad bad after hour service.

I was struggling with my WiFi signal since the 22nd of December 2018. After numerous watts-ups and phone calls, I struggled to get assistance. There was no signal between my router and the service provider. Eventually I looked on the pamphlet in the router box. It said I must press the RST button for 8 seconds, so I did. All was OK except that my WiFi was no open to everyone. Call after call, watts-up after watts-up, I am still struggling until today. I was told to never press the RST button, why does the pamphlet say that? I will now have to pay them call-out fees so they can reset my password. What the hell, I pay for a service, I pay for the installation and don't get assistance when required and then I have to pay for the call-out.
