Bad Service

Dear Sir/Madam I took a cell phone upgrade at CellC Forest Hill in Centurion on the 20th of May 2020 for a Huawei P40 lite. Unfortunately the Cellphone fell and cracked the screen on the 3rd of July 2020. I then learned from someone who works for Huawei that I’m entitled to a free screen replacement within 100 days of purchase provided the device is registered on the Huawei website within 7 days from the date of sale. I then took the cellphone back to CellC Forest Hill for the replacement of the screen because they didn't inform me about this 100 days offer hence I never registered for it on the Haiwei website. To my surprise they said they were not informed by Huawei about the 100 days offer of a free screen replacement.So I asked who should account for this because I bought my device at Cell C thus can't go to complain at haiwei, and was never given a proper response. I have been sent back and forth with regard to this matter without luck or anyone taking accountability. CellC Forest Hill wants me to pay for the replacement of the Screen. I fill my consumer rights are violated by CellC as I bought the device from them and they never informed me to register the device on Huawei website to be able to enjoy the 100 days free screen replacement benefit. I asked for a reference number for my complaint and even that they are refusing to give me.
