Cannot even help with a port out

So basically I wanted to move away from Melon to Vodacom so for 2 days I spend it a Vodacom shop asking what needs to be done but I get told to do ABC which I did Vodacom says they need that I will get a sms saying port has been approved and then they can issue me with a new SIM card however melon say no the port is already happening but how can it be happening when there is no SIM card for the number to go to, I have been sending message after message to them with not even a respond on what I must do, I even sent them a pic of the error message from Vodacom but not even a peep or something saying we looking into it

I really looked like a idiot in the Vodacom store telling them they are waiting there till they close cause of no response
