Vumatel fibre

I am sick and tired of my fibre line going down everymonth , payments are made on time i expect 100% of the service delivery i paid for. I dont even get reimbursed or extra days added on for all the downtime i experience this is really frustrating. I cannot understand how the other tenant in the yard and i have the exact same routers running on the same type of fibre line which is the 40mb but he has no issues at all yet mine everymonth is continuously going down for more than 3 days a month and now going into the weekend when it's needed the most. You guys better resolve this once and for all or you're going to lose a loyal customer and all the other people i made join this service provider.
