Cancelling cell phone contract within 7 days Problems!!

Hello Peter,

I purchased a Huawei P20 Pro on Saturday and during the two days i noticed that the phone had alot of lagging and battery issues. I then returned the phone to Telkom on Monday and they said that they can send it in to get checked and I wanted to know whether i can rather change my contract to a different phone as I am not satisfied with the problems I found. They said that if theres something wrong, they will only be able to give me a new phone and if i dont want the phone I can cancel and pay in the cancellation fee.

The cancellation fee is over R 11,000!!

I dont understand why I need to pay in a cancellation fee thats so high. I dont want the phone anymore. I find this unfair because i've returned it within 7 days. The problems I encountered with the phone is not me. Why am i not able to rather choose a different cell phone ?
