Poor service unfair cancelation

I have policy with sanlam indie for 3 years now with a premium of r387 I chatted to the consultant to change my debit date They rep**** saying there was technical error they will refund me r1431 premiums as my policy will be canceled and suppose to be canceled in March already I told the consultant I policy was reinstated in April already with no waiting periods They advise I missed one premium They are unfair and dishonest Nicole the service advisor assisted me Stating when she reinstated my policy she did not communicate with the other relevant department I'm sad and shocked with they service after 3 years I am canceling all my products with them. My advice don't take any products with sanlam. I asked for all my premiums back They only refunding me r700 back.
