Request to cancel the insurance on all the cell phones that I have with Telkom

Good day

I have sent numerous emails and called Telkom about the insurance on my contracts that I have with Administration Plus on *** or email ***

I have had no response no feedback nothing. I called & sent emails & have not received any feedback. I received my Telkom invoice on 1st June and the insurance is still on the invoice for this month. I cannot afford to pay for both insurance premiums. I have sent proof of the insurance that I have with MyWay, meaning I will be double insured. I need your insurance to be canceled. I cannot afford a double debit. My bank account will go into a minus because of this, as MyWay debit order is for the 20th June and yours is for 25th so when your debit order goes off, I wont have enough funds and then my bank account will be affected and my credit score as well!

Please can you answer me on my email.
