Escalation to Senior Management

I reported that my fiber is not working last week Tuesday, I call twice every day and have not been assisted. They keep on telling me that the Manager is going to call me. I can't even cancel the month to month contract because I have to give in 1 month's notice. I am working from home and had to but 2 gig data every day for the past 5 days so that I can be able to work. I have requested to speak to the Manager and have been told he will call me back and still nothing. At this point I just need the wifi to be sorted out since I cannot canel with immediate effect. Anyone with the CEO's contact details, please provide them to me
