Vodacom insurance

I am a first time Vodacom contract user and I am really not impressed with the Insurance that they use. I took out a new contract in November this year and at first I did not take out insurance. I got a phone call on the Saturday after I got my two phones from the insurance to say that if I do take out insurance on the day on both phones that I will get the first month free and my first debit order will only be processed at the end of December 2022. Then end of November came and I was invoiced for November and I tried resolving this but the accounts department said its the sales department and the sales department said its the accounts department. Eventually I gave up till now end December where my debit order bounced because the insurance invoiced me for November and December. I have been on the phone where they just transfer me to someone new each time or the line goes dead and when one of the Vodacom consultants eventually got me through to someone from the insurance there was not much of assistance and I am still waiting for an email. I am very frustrated because of this my debit order cannot be processed and we stand a chance for the Vodacom line to be cut off due to non payment
