Cell c is the worst place to take a contract with

I took out a WiFi contract with them a while ago. I then upgraded to the connector package for 1000GB for R1149.80 pm. When I contact them to attempt to reduce the package they are telling me that I can’t reduce the package because cell c doesn’t have that package anymore. When I got transferred to the upgrades department, they told me that customer care must first assist with moving my package from connector to smart data thereafter, they must assist me with the downgrade migration. When they transferred me to customer care, they told me that it must be done by the upgrades department. Then upgrades say that only help with upgrades not downgrades. There seems to be a miscommunication between the upgrades and customer care department and all of that is prejudicial to me. I do not understand why I have to be prejudiced because I want to pay a lesser amount for WiFi. I don’t need that much WiFi therefore I can’t be prejudiced simply because cell c doesn’t have the package anymore. I need my package to be reduced. I can’t wait to be done with cell c so that I never ever take any more contracts with them.
