Network Problem I cannot make outgoing calls, I cannot receive either

Since 13/04/2018, till today 14/04/2018 I can not make outgoing calls n Pretoria West even caretaker of the building cannot. The gate is opened manually because we cannot go in and out. I did search network change to Vodacom. When I make calls I get a notification that Vodacom SA is not available. I cannot call even your customer. I was lucky to call them @ 03 AM, call drop they cannot call me back voicemail. I did speak to Lonia Matthew she said she cannot log a call I don't have 3 numbers, I ask to speak to team leader Themba/Temba Ncube call drops. I have received 4 voice messages I cannot listen to them because I cannot call voicemail number. This is a huge problem it needs to be fixed. My MTN # is ********** 241, because you cannot get hold of me on my original number
