Poor service

I have since signing up with Vodacom Fibre, trying to have my correct speed as per my contract corrected however they have been stonewalling me with incompetence from front line, team leaders, escalations team, customer service to even their social media.. for ease of reference here is one SR***.. not sure if anything will be done for you have proven to me that no matter how many calls I make you still not interest in fixing the problem however the blame gets placed on Nokia.. . Anyway maybe the best thing is just to close my account and right off as a bad experience .. But will definitely in all my presentations on customer service use my experience to advocate not to use your company...
