Bad Service - Unable To Provide Delivery Details

After receiving bad service from my current service provider I app**** for a new contract with Cell C. I did an online application and provided the required documents after which I was told delivery will take place within 5 days. A week later I called to follow up only to find out the incorrect device and plan was selected. The request had to be sent back and rectified. Now, another week has passed and they are still unable to tell me when the device and sim card will be delivered. A request was put in a week ago to port my number over to Cell C, when I called to follow up on Saturday I was told that the port is hanging in between two networks, also that they are unable to provide me with an update on the delivery as the team responsible do not work over weekends. I have asked for a manager or team lead to contact me and I am still waiting. I am seriously starting to regret the decision to move to Cell C! This is by far some of the worst customer service I have received in a long time.
