EMTY PROMISSES and NO SERVICE

I have been struggling to get Vodacom to come and sort out no signal and there booster that they promised will take 2 weeks to fix that was in December 2016 i have been using same ref number . A2-20ju-78BZF since then and every time i call in and hold on for at least half an hour the just say it will be fixed in two weeks time its been 9 months now and still nothing . We are a company and cant work like this ! If i try to get hold of a senior manager or someone i get cut off i am so disappointed that they do this to there customers i am going to move to another service provider maybe that will help ! I feel this is unacceptable. now the new story is they loged the same ref number but just in June 2017 how does this work ?
