Cannot take vodacom at their word

Why cannot vodacom stick to what they say. I phoned the call centre on 1/7/2020 to query a supposed email sent by vodacom re my email account being breached & if I do not verify my account my email or it would be deactivated on 3/7/2020. I wanted to confirm that this was actually from vodacom. The call centre operator assured me vodacom would phone me within 24 hours. My reference number given is ***. Needless to say I am still waiting for the call. Is there no sense of urgency at vodacom
