Cancel my contract or give me a different brand to choose from

Telkom is pathetic to say the least , just after 4 months of having the contract within that time I’ve experienced issues with the device and reported that it became bad and at first thought it could be because it simply required an update however it updated every single day , what it was updating so often I do not know and the freezing problem persisted eventually I got them to fetch the device only for them to tell me it needed a part that needed to be shipped to fix it , I mean this is a brand new product that I hardly used needs to be repaired and I need to pay for it whats the point of having a warrant or a new device that you have to pay additional fees for , if i knew they were going to sell a faulty device to have me fix for the repair i would have never gone with telkom i want them to either pay for it or cancel my contract and I do not want to pay a cancellation fee for a damn faulty device
