OUTSTANDING REFUND AND USELESS STAFF

I called Vodacom mid July 2020 after I received an email to pay an account and I called them to arrange a debit order which did not go through. I called them them again few days later just to check what the problem was and an agent on the 27 July told me that they do not see any debit order and i asked her to put it on record that i will pay eft and send pop after payment and she must just make sure no debit order runs for July month.To my surprise the debit order went through on the 28 July and I called same day between 9 and 11 am..I spoke to a manager who assured me that they will refund the money in my bank account and till this day I am still waiting for my money..I called them every 2 days to check how far my refund was and they kept on telling me that they do not see anything on the system which means repeating my story countless times to agents and managers until my calls were blocked.I tried calling them with a different number and asked to a manager and an agent told me that all managers went for training and took my details for a manager to call and never received any call from them..I just want my refund and so that i can look for a better service elsewhere.
