********** Port Out

I've been a Vodacom client for 7 years. I received an sms from Vodacom on 2/04 saying that they'd received a request to port out my number. I never asked for this and was concerned because my credit card had been ****** a few days prior and I was receiving unsolicited sms's with an OTP to change the card's pin. I immediately phoned the number Vodacom supp**** and was told the request was from MTN. I obviously asked for the port out to be cancelled. Then I physically went down the local MTN store and asked them to cancel it from their side (they did). Then I physically went to the Vodacom store and asked them to protect my account. They reassured me a port out without my consent \couldn't happen\", but nevertheless \"flagged my account\". On Sun 3/04 I received another sms from Vodacom saying they'd received a new request to port out my number. I went through the same procedure, phoning Vodacom and going to the store. Again I was reassured. At about 8pm that evening, a 'No Service' signal came up on my phone. I immediately phoned Vodacom: my number was no longer on their system. I phoned MTN: the number was on their system and linked to an unknown prepaid account. How does this happen?"
