Totally and utterly useless customer suppport.

Vodacom has the most useless customer care out of all the service providers. They are not helpfull, and if I could I would give them 0 starts. When you dial 083135 you get a menue. When you select the billing query, you get told you will be send an sms and the call is cut. The sms is of no use. I have tried multiple option. I have send a mail to customer care and I have received a mail back that I cannot be assisted on that platform. I tried whatsapp and I was told I could not be assisted as I am not submitting my query from my vodacom account. The query relates to my Vodacom Data contract. How the F#$% am I suppot to whastapp from that account? I am 1 step away from cancellilng my Vodacom contract.
