Worst Service ever

I have agreed to the Vodacom Fiber on 11 November. I have been told that the installation will happen within a couple of days. After no response, I called the service desk on 13 Nov. Spoke to Dinico (pardon spelling). He confirmed that their app to schedule the installation does not work, they will call me to schedule. (Reference SR***) After absolutely no response again, I phoned on 20 Nov. Spoke to Ameer, who again made promises of a couple of days. Again after absolutely no response, I phone again on 3 Dec. Mpomsi apologise abd said they will install on 5 Dec. Again absolutely nothing!!
