Line cancelled with no reason

Please, I desperately need help, Vodacom cancelled my number for no reason at all. I was part of the Autopage subscriber base and in the port process, my number has just been cancelled. Autopage say that its Vodacom's responsibility, but no-one at Vodacom (and I have made 20 calls) can help. Please please please, this is my work number, I have had the contract for 15 years and there is no reason why my number should just be cancelled. Im desperate. Please help
