Vodacom's incompetence

I have been on contract with vodacom for years but find myself deeply disappointed & inconvenienced by this service provider & *********** call centre as im without a phone for a month now & keep getting the redundant response to please wait for 48 hrs for them to unblock my sim thereafter another 48 hrs as they blacklisted the device when unblocking the sim, this is a story that has been playing repeatedly for the past 4 weeks where not even the team leaders are able to rectify their error, leaving me out of contact & isolated during a pandemic where everyone & everything is now online.
