Worst customer service ever!!!

I opened up a contract on Mon at mall@carnival Vodacom. After filling out all the forms & choosing a plan, the lady said that there is no stock, they will be receiving stock on Wed morning at 11. She said that she would call me. I asked her is there any amount that I need to pay, she said no not at all, just pick up the phone. Wed morning I did not receive a call so I went through with my boyfriend at about 2.The man that helped us said that the lady was not in & that no stock was brought in. I asked him to call another branch. Their power cut due to maintenance so he used my boyfriends phone and his airtime to call. He found the phone at Lakeside mall. We asked for the manager. The manager was completely hopeless & said that we can take our forms to lakeside 2 open the contract. @ lakeside they informed us that the whole contract was wrong, it was old & prices were wrong. Also that we needed to pay 48hrs later 4 the phone. I went in today to speak 2 the lady about her wrongs, she was completely rude, shouted, refused 2 give her name/surname, called me stupid. Manager was just as rude & kicked me out the store. Worst service I've ever received!! Disgusting!!!!
