Number deleted on network

I logged a complaint on the 4th of January about the number which I've had for almost 11 years ***), which was deleted off the Vodacom system. On the 5th, I received a response from Vodacom Consumer Website Team saying that one of their consultants will contact me. <br> <br> On the 10th, I logged another complaint as no one had called me then. Again, the Consumer Website Team apologised and advised that one of the consultants will be in touch. Up until today, no one has bothered to call me.<br> <br> Please advise who do I need to speak or escalate this issue to, in order to get it resolved asap. I want to take a contract but need to get this number issue sorted first.
