Vodacom - who do you blame your poor call centre connectivity on ???????!!

Been going around in circles since September last year to get my contract upgraded . Have had calls cut on me , consultants say they going to do things that they don’t and even been to a store with no luck ! Pls cancel the upgrade on your system that show as being done but actually wasn’t ! I’ve been a client for almost 13 years and have many contracts with you if you can’t solve this issue I will cancel all dealings with you . This is nonsense .
