Cant get hold of Vodacom

I decided not to upgrade my contract as yet because I cant find anything that is suitable so I want Vodacom to remove the portion of the notebook that I took with my last upgrade (R168.70). but cant seem to get hold of any one, tried the online bot but had no success. Sent an email yesterday (received a reference number) and still not a word from Vodacom, and the 24 hours are up. SO not sure what to do anymore. I have now tried chatting online, then sent an email and now trying this avenue.
