Terrible Service

I have been a customer for 12 years now. Never experienced any issues until recently. For the past 4 years I have been on a uchoose flexi contract, at the beginning of this contract I received 2GB every month and no airtime only to discover that the sales agent was just trying to make a sale and sold me the wrong contract. Eventually after 4'months the canal walk staff pointed out that the agent in cavendish ripped me off in order for her to meet target. They fixed it however never offered any sort of compensation, I was ok with it as I work in customer service and let it slide. After it was fixed up I started getting my airtime R200pm I then trangsfer that into data. I have been doing this now for the past 3/4 years with no hassle. Now since May this year I have been paying my bill and agents would confirm the amount. I have been receiving texts saying I need to makw payment. Eventually I go into the store and they advise that I have not been paying my bills meanwhile I have all my slips. My account then suspended due to short payments being made. I then went into the store where I was advised that I have been purchasing data but choosing the recurring option. I told the agent that I have been using the *111# self service option and never had this problem, he then told me that I need to make sure I choose the 30 day only option I advised that there is only a "30 day" and a monthly option which I would not choose. He then said that the options changes sometimes, which did not make any sense to me at all as I have been doing the same thing all the time and never had a recurring issue. I have called into the call centre today where the agent was not helpful at all. I asked if we can have this escalated or investigated and the agent said no someone must have used my phone to do this. She was not helpful at all. I even advised that I have the text messages to prove that I have been purchasing once off data but no one is interested. I am very disappointed in the service I have received from Vodacom. I am considering changing providers. Really a pity as your network is really good. You guys really need to employ people who have customer service s****s or people s****s as your staff do not have any of this etiquette.
