Bad customer service

I have an insurance with Absa and im experiencing issues...Last month they debited my account few days later the amount short by +/- R20 returned into my account and they advised insufficient funds yet I had money.. received an email saying they will double debit and the double debit went off on the 1st of June but again on the 04th if June money came back into my account short saying insufficient funds.

I called for assistance they told me it showing paid they will call me today...they don't have banking details for me to make cash payment, I didnt receive the call.

This morning I received an sms saying my policy is cancelled called 1st time someone answered and didn't speak, called again Palesa answered and advised to call me back but didnt call, called the third time a lady called Siphamandla answered and cut the call on me.

Im not happy with the service and I need someone to call me urgently as I need to reinstate my policy and make payment.
