FED UP WITH BAD CLIENT SERVICES

I phoned Vodacom Customer care and spoke to Rachma, she tried to assist me, as I had R300/R330 rand extra debited with my Aug debit order. I asked her how can this be possible. She said that I bought a 1 GB recurring data bundle on 1 Jul and 01 Aug. Without giving me a chance to ask questions or reply, she tried to talk over me so that I must keep quiet and only she can talk. I am a team leader in a contact centre and I will never ever allow one of my agents to have this tone with any of our valued subscribers. She then hang up on me telling me she will phone me back.....she phoned I asked for her manager. No return call yet only a sms saying that I have used the "2GB" and they will give me R149 airtime for goodwill....Bull****. How come they allowed 1GB purchased if ever done, if I get my monthly top up of R200 on the 1st of every month, why not deduct it from there my airtime they MUST give me on contract I took and why debit me over R300 for two months data? So irritated by this bad service!!!
