Vodacom charged for email which I did not sign up for

In the 23 Dec 2022 I received an sms to say that R173. 49 will be ducted on the 28 December 2022 but I only pay R115. 00 every month. So I phoned Vodacom immediately and waited for over 20 min on the phone before being help. 09h05 to 09h21 then 09h21 to 0933 then 09h33 to 09h45 36 with the consultant who could not help me all he said was that the extra charges was for the email I told him I did not agree to the charges and then he said he will cancell it immediately but I must still pay it on the 28th of December 2022. This is so unfair to pay for stuff you did not agree to o. He said his team leader will phone me at 11am today the 21 December 2022 it is now the 30 December 2022 and the team leader still did not call me. This is such unfair services from Vodacom
