VODACOM POOR SERVICE

I had blacklisted my phone on the 2nd August 2021,then it was found at work a week ago while they were deep cleaning the offices,i called vodacom and requested that they unblacklist it,i was send a form and was told to email it on Monday the 6th September 2021 at 12:38 to *** also to *** and today 11th September i called vodacom call center to check how far they're with the process since i was told to keep my phone off for 48hrs and i was shocked to be told that they didn't receive my email and there's nothing on the system showing that they have made the request to unblacklist it.Guys this is unprofessional.
