WORST SERVICE MANAGER

I bought a R79.00 once off 500mb monthly bundle on prepaid that auto bought me a whatsapp 1gb bundle i did not want. When going through to the call centre i was accused of buying it myself and when asked to reverse the whatsapp bundle that i did not ask for or manually make a purchase of, i was told its not possible. After being upset by the consultant and i told them and their manager this is ****...the manager Mr Themba Mthembu says my language is too bad and he will not assist me to reverse it. Vodacom has now purchased for me something i did not need and the manager has no way to calm someone who has been upset by his team instead he frustrated me further and told me he will not reverse the transaction.Honestly in my view he is not fit to be in customer service as he only makes the problem larger instead of turning an upset customer into a happy one. Thanks for using my money and abusing my right to purchase what i want with my money. Also no thanks to your so called customer care department for not assisiting me through my frustration with a technical difficulty.
