Vodacom frustration

I will rate them a zero at this point. My WIFi stopped working 3 weeks ago, I've been calling Vodacom Fibre every second day ever since. All the agents keep asking for the same information but no progress. Finally yesterday I got a sms from Openserve to say they will come today but nobody came, when I called Vodacom I'm told that Openserve is saying the reference they gave me is incorrect they want one with letters, where am I supposed to get it if they didn't send 🤔 Vodacom is also not able to assist me with their sub contractor. I have a contract with Vodacom but I'm being sent from pillar to post for 3 weeks now. My issue can't get resolved. I don't know why they are not saying if they can't help me to move on to another service provider. Vodacom even closed my incident without being resolved, I don't get it 😕
