Worst service ever

I app**** for Vodacom Fibre 3 weeks ago. I received an email last week confirming that they will install the Wifi on Monday 11th Sep because the technicians had finished what they needed to do in terms of infrastructure at my complex and some Gareth guy was going to call to confirm time. Since Monday I have not been able to get any info as why this has still not taken place, and all the customer services numbers and scheduling team numbers go unanswered. I have never seen such blatant disregard for customers. Arrogance at its worst.
