Pathetic internet service and tech support

I am almost one year with this company and I have had nothing but headaches. I have an adsl line and wifi router with supposedly unlimited internet monthly. However since I signed up I have had endless problems with my internet. The signal keeps dropping, I have to restart the router about 10 times and then reset it because restarting just won't work. Tonight was the last damn straw. I called in to tech support because been struggling with internet connection over an hour. I sat on my cellphone for 34 minutes and the call got cut off because 10pm is closing time. Nevermind you have a customer on the line with a legitimate problem which the tech officer has been trying to resolve for 30 freaking minutes. Now I m stuck with this problem and your call Centre is closed. Your company is pathetic and service delivery belongs in the toilet. Attached shows I am connected and shows signal strength but with an exclamation mark meaning no access. I am so happy my contract ending October because another year with your pathetic service delivery will give me endless grey hairs. I will post as many negative reviews about your internet to as many people who will listen on all social media possible. You have no problems taking my money every month but you cannot and will not assist a paying customer. Pathetic
