Unauthorized debits on my account

I was quoted by All life and accepted quite ..a few days later I was quoted by another insurer which was cheaper than All Life. I then called to cancel the quote with All Life. Three weeks later they debited my account....I couldn't reverse the debit order. They then called 2 months later to ask if they can requote me....I agreed and the consultant Moeketsi Ndara promised to call back however a day later before I was required my account was debited once again. I called the consultants no response....I sent an email no response. I then sent an email to customer service and still no response. I am not happy with the kind of service and even after I asked them to contact me back to date there has been no communication from them.
