Very unhappy customer

In november of 2018 i took out 2new data contracts wiht cell c the sim cards were delivered to my house by ram couriers at that stage with it being the holidays and all i did not use the sim cards untill January.. Or i tried to use them but turns out that cell ce sent me the incorrect sim cards i reported this on Thursday 17 January and i was told that cell ce will contact me within 25 workings hours to perform a sim swop which i explained i wont be paing for it as the mistake e was made on their side.. It has been 6 day and more than 24 hours and i have not heard anything from cell c yet i made a nother call yesterday the 23 of January an i am still waiting for a response and in the meantime im being billed for a service i cant use. If anyone at cell c is willing to help me pleas contact me if thats not to much to ask
