INTERNET NOT WORKING

I am beyond exhausted from the run around i have been getting from you guys. Since January I have been reporting that my router randomly disconnects and internet wont be available for hours on end . No amount of restarting or resetting the router works . For the past ,almost 6 months I have been barely using the data allocated to me,not by choice but because of this issue . I have called numerous times, chatted to consultants on your what's app platform and to date i have not received any assistance. For the past week I have been communicating with ***, who has suggested moving the router to a window and admin resetting which has also failed to resolve my problem. I have since asked that the internet portion of my contract be canceled WITHOUT CHARGING ME effective from the 31st of May because I am tired of paying for a service that sometimes works. Something changed on your side from January because since then,besides this major issue I can't even see data balances on my side. I was also told to delete the app and download it again,which again didn't work. I am tired ,I work from home and have had to buy data out of pocket which is ridiculous when I have a data contract with you guys. Can I get confirmation that the internet portion of my contract has been canceled WITHOUT CHARGE by the 30th ,I refuse to pay for internet thats not working.
