No incoming calls, no one willing to assist

I haven't been able to receive incoming calls from Friday 08/03/2019 due to an error made by a Vodacom employee. My number was cancelled when I called vodacom to enquire about my account, Instead of them fixing their original mistake they made matters worse by cancelling my number. I haven't been able to receive calls for 4 days now and I am told that my query might be sorted in 7 working days. Can you please look into this and all my lines should be fixed urgently.
