7 Day Out of Box Fault Policy

Took out a contract at the branch on 12/11/2015 for Huawei P8 Lite, started having issues with the cellphone almost immediately after I started using it. The phone freezes, network drops, requests I accept marketing material when trying to access files, dual SIM doesnt work and both reset network when phone is restarted etc. I took the phone to the branch on 17/11/2015 and requested a new phone phone. The Huawei Specialist asked that i leave the phone for them to check whats wrong and when I got back she told me it was a factory default. The manager then said it needs to go for OBF assessment and only when approved then they can issue a new phone 7 - 14 working days after receiving the phone. HOW IS THAT IN LINE WITH THE CONSUMER PROTECTION ACT???? When I then said they must cancel the contract and I will rather take another contract with a different phone the manager said once again I first have to wait for the assessment. I think the service from your company is a disgrace and demand my rights be enforced immediately!!! I want feedback from Cell C ASAP as I am not prepared to wait 7 days because YOU SELL FAULTY PRODUCTS!!!
