Poor customer service

Vodacom is an *********** company. It’s always a hustle to get assistance. I have data that is due to expire and they have a roll over functionality that we can’t even utilise. The system states that you can buy data and automatically the data that is due to expire will take the new date of the new bundle but that is not the case. Tried calling customer services there is no option to speak to a human . Tried tobi on Vodapay app I was told to WhatsApp or call. Tried the WhatsApp totally useless. An operator called only for the call to be dropped. I don’t know why I even bear with this nonsense I should just change my service provider really
