Bad service

I sent an email to *** on the 18th of November 2024 to request my iPhone 13 which I reported lost two months ago to be unblacklisted, Until now it hasn’t been resolved and every time I call the call centre to enquire about my query, they tell me that my query has been closed but my phone is still blocked and there is no communication which is very ***********. I am not happy with the service that I got from Vodacom
