Mweb bad service

I have been having a poor customer service from Mweb .I have been utilizing their internet service for almost 2 years with no issues , however since now recently (for the past 2 weeks ) I have have had zero coverage on my signal , I have called their technical support desk numerous times and unfortunately they have said that they cannot give me a turn on around time on my request, and As a result it’s affecting my work as 80% of it is internet based . As we speak I am typing this message cause it’s working but come 10am until 11pm I am inaccurately offline , I am honestly not happy with the service that they have provided me with this far as it’s impacting my livelihood.
