Data bundles not loading, vodacom doesn't answer calls

I've been trying to get hold of vodacom since Saturday. I purchased a 1 gig data bundle via the vodacom app for R99. The data bundle did not load however on the app it says the data has been provisioned. The data never loaded and I've had to purchase data since then. I tried to contact vodacom yesterday but the call centre was closed. I called vodacom today on the number *** when dialling that number you are transferred to the contracts department. I was then transferred to prepaid, I was put on hold saying there are a number of high call volumes and that I should call back later. An automated bot tried to assist but then said it cannot assist with this query. I am unable to contact vodacom at all and I find this level of service disgusting.
