Misled by the Miway consultant

I am highly disappointed and out of words by one the staff of Miway insurance, I received a text that my premiums will be debited on the 21st of December,I went out of my way to contact Miway to let them know that they shouldn't debit on that date, because my account is sitting R0 they should move it to the 25th or after that date. I was assured by one of the consultants that she has moved my debit date to the 25th"happy days" On the 23rd I receive a text stating that they attempted to debit on the 22nd but there were no funds.

I am highly disappointed by this company that I trust so much,now the debit order has lowered my credit score,after informing them about my financial situation yet they still went on and debited

Honestly I am considering cancelling my insurance with them, because their consultant mislead me If you don't believe what I am saying listen to your recordings. Regards
