CELLC bad telesales

Hello peter, I recieved a phonecall from CellC on 5/02/2021. They sold me a contract for 50G monthly mobile wifi router for the amount of R 299.00 p/month. They couriered it to me on 11/02/2021. Since 18h30 on the date of delivery, I have been calling CellC customer care, trying to activate the product for use, as they did not provide any instuctions on how to activate the product. I struggeld with incompentent consultants up until 0h20 that night, with vague information and wrong or unusefull information regarding the activation of the product. Since 14h30 12/02/2021until 17h00 I have been trying to cancel the contract with no success. The keep on transfering me around to different departments as to avoid the problem when I try to speak with their consultants. They gave me a 5 day "cool off" period in wich I may cancel the contract. I can see that this is going to cause problems for me. Can you please help me to let CellC assist me in cancelling the contract?
