Port of number

I visited the Gateway Vodacom shop in January to cancel my contract at the end of February 2016 and have it on prepaid and my number ported Reference Nr***. It was not cancelled . I was assisted by Travis. On the 15th April I was at the shop again and was assisted by Nadia who told me nothing had been done. Reference ***. She called a number and late yesterday the account reverted to prepaid and I was assured ready to be ported. Since then my new service provider has been trying to port the number, I keep receiving 'declined' sms. I spoke to Victor at the Vodacom port division this morning, only to be told by him that Vodacom has had technical issues for the past month and no numbers can be ported!!! I find that totally, totally unacceptable. He said I could try again on Monday and every other day until Vodacom resolves the issue. A technical problem, seriously Vodacom, you leave a bad taste in my mouth after 15 years of service!!
