Absolutely poor service

I am very disappointed in service provided from Vodacom Fibre in Secunda Mpumalanga. No support from Mpumalang Regional Manager. I have loaded 300 service requests and still have issues that are unresolved. I have been struggling with my fibre line for the last 2 months and still every service request reply is test and see if improved. Paying for a service that works only half of the time. I have personal contact with many technical people from vodacom and the regional manager but the only reply a person get is to load a service request. So how many should i load before something actually gets done??
