Vodacom Contract

Last year June I took a contract 24 months with Vodacom which the contract must expire in June 2022, yesterday I called Vodacom to check if it is possible to settle my account, to my surprise I was told that my contract will end on October 2022, which I don't understand as it will be 28 months I asked the Consultant to check and she couldn't give me a proper answer. She advised that she has logged query and I will get sms with reference number however I'm still waiting. I'm not sure if this is what vodacom treats their loyal customers as I've been a loyal customer of vodacom since 2002 and they will push me to port my number.
