Pineapple Insurance is the worst

I requested a quote from Pineapple Insurance for my car and was quoted about R 700 and when they did the the debit order mandate for approval,it was now R914 for policy no:...... and I declined this ,and now that I am calling them to enquire and cancel this ,I am not getting through and they have already deducted a pro rata amount for the comprehensive cover..I want to cancel this policy becausing this is ****ing people in that they quote a lesser amount but they want to deduct a higher amount.
