Bad service

Received a sms from Vodacom at 22h00 on 6 April 2015 to inform that a request was received for a sim swop. I only saw the message on 07 April and called 111 immediately from another cellphone as the sim swop was successful. The person at the call centre told me it will take 24 hours or I can do a sim swop at any store. I told her that I am not prepared to pay for something that I did not do and she said they will contact me. Nobody contacted me. I phoned them every day, and every day they promise to phone me back. On Friday, 10 April, somebody phoned and said it will be sorted by the end of the day. My sim card is still not connected.
