Pathetic service from Vodavom fibre

Pathetic service from Vodacom fibre. Internet down or intermediate. Faults are logged monthly. Resolved, however for a week or two only then the same problem starts again. They ensure that I have internet for a moment or two every 24 hours as not to be forced to give Ct. Can't change service provider as this Vodacom has the monopoly in the Estate. And now they will increase our bil!!! Pathetic!! I will definitely ad is all I know and meet to avoid this useless service provider
