Complaint -MRP Mobile -Free Sim ****

I received a phone call September 2019 from a Mr Price consultant thanking me for being a loyal Mr Price customer, telling me Mr Price is 'GIVING' all loyal customers a SIM card from them, giving the empression that the sim and first R100 airtime is free and that the delivery will be free. Being nice I comp**** and said that it was fine to send it, since I would not be paying anything for it, not even the delivery. To my surprise they charged me R129 for the SIM card as well as R100 for airtime. I only saw this on my October statement on and immediately called them telling them that I was not aware that I would be billed and did not want the sim as I have a full time cell contract. They were very annoyed and did not try to hide it. They told me it would take TWO days to get back to me after they have audited the initial phone call. I feel like I have been literally ****** from, as you use words so ***** that you are selling something to someone without them even knowing that you are selling it. I have asked them to cancel the sim as I have not used it at all. What a bad experience I want to close this account as soon as I can but I refuse to pay for something that was forced on me and to my knowledge was COMPLETELY free. I will no longer be a as you say 'LOYAL CUSTOMER' if this is how you try and cheat your loyel customers. Mr Price will not see me again and will no longer be receiveing any support from my family. Really Annoyed and mad ex Mr Price Customer.
