Contract Cancelation

On the 5th of May I took out two cellphone contracts at telkom.. I never got the chance to explore the phone or do data transfers. However on the 7th of May I decided to explore the phone, and transfer my data...

Please bear I mind I experienced all this on both phones.. The phones were extremely slow. I did not work on 5G like they explained. The data connection was poor.. The phone take 10 minutes to restart. The photo quality on both phones are extremely poor after they told me that the photo quality on the phone is good. When I take a screenshot of something it says "can't save" due to storage space (how is that for a brand new phone) Overall it was an unpleasant experience. I went back to telkom on the 8th of May. They refused to help me nor help me take out new phones (different brands) I didn't mind paying extra if that was the case.. They refused I then said that I want to cancel my contract with immediate effect. They refused to do so. I called customer care. They also explained to me that I can cancel my contract.. However telkom refused to help me. I then left both phones there. And left. Could you kindly assist with canceling my contract I want nothing to do with telkom anymore
