Complain

I got a call from Vodacom around October/November for renewal of my contract which I did on line with the amount of R229 every month and today I phoned Vodacom customer care and I spoke to a lady by the name of Shereen and she tells me that amount I am Paying is R349 instead of R229 and the insurance of R320 which amounts to R660 which I didn’t not agree with Vodacom about and she referred me to Vodacom third party company
