Im so disgusted - I am honestly at my wits end

Vodacom has to be the pits of all hell , About two- three week back I complained about data jut going off my account without me being on many socials, I had a gig data loaded at 00h00 and its only 10h18 and data is gone -I have mostly been on Whatsapp but my data is gone , the two consultants that I had spoken to on my last enquiry did not assist instead they returned the funds used to purchase the data which does not aid at all – Once again today I have purchased 2 gigs ( 500MB X 4 ) in a space of two hours please note everything everything depleted – I am so so angry , the agents DO NOT KNOW What thy are doing there I am so annoyed haibo
