*********** manager not refunding me and breaking promise!

I upgrades with vodacom first week in December 2017. I received my 2 handsets but vodacom neglected to send the smaller sim cards for the handsets. They also admitted that it was supposed to be sent together themselves. This meant I had to wait another week for delivery meaning I was unable to use my new handsets for which I am paying... so I complained and was transferred to the male manager Yolanda. He told me to purchase 2 simcards and send him the receipt on 5 December 2017 which I did as he was going to credit my account in January 2018. I sent the mail with the receipt = zero response. Sent it again to beg for acknowledgement of receipt = again zero response. Now I see that no refund was done to my account. This makes me incredibly MAD! I do not understand why loyal customers are being treated this way... I want my money and want some compensation for my time, effort, petrol and money for having to get the simcards in the first place. Even when I went for the sim cards there was a issue for which I had to sit there for about 3 hours for something Yolanda did not cancel. My parking fees were like R 15. I am being inconvenienced incredibly now... Vodacom, this is not what I expected from you!!!!! :-(
