Cancel contract with immediate effect!

Not even worth one star. I phoned Vodacom on Monday 25/05/2020 icw my data. I get 10 gig of data on contract from Vodacom. Usually it lasts up to the last day of the month. In this instance I topped up with 1 gig on Sunday because my data was used up. Early Monday morning I realized that the 1 gig purchased on Sunday was also used I topped up again with 5 gig R349.00. I phoned Vodacom shortly after that and I spoke to a lady called Mpho to get assistance because the 5 gig didn’t reflect. She then told me she’s going to escalate my request because she can see I bought data and it wasn’t allocated to my number. She assured me that it would take 24 hours then I’ll have my data. Well it’s now more than 24 hours and still don’t have data. And I had to buy another 1 gig in the meantime. Today I spoke to Bongani a very rude person who at first refused to provide me with an email address in order to send proof of purchase to Vodacom. I just renewed my Contract with Vodacom and want to cancel the contract with immediate affect I want response from Vodacom! Services from Vodacom goes from bad to worse Susanna Sieberhagen
