Poor srvice provided by Cell C

Cell C is continuing to lose customers because of the poor customer service that they provide to their customers. I lost my iPhone 13 Pro Max around January 2023. I called Cell C to blacklist my iPhone and luckily the iPhone was found and called Cell C again on 13 March 2023 to request Cell C to unblacklist my iPhone. I have since sent all the required paperwork including the affidavit. As of today my iPhone is still blaclisted and called Cell C so many times without any assistance. I have been with the Cell C contract for so many years. This company is useless and they don't know what they are doing. They don't know what is the purpose of the affidavit and what the affidavit entails. My recent case number given by Cell C is ***) my case is still pending and not resolved. What a shame!
