Funeral policy **********ly billed on the account

I finished paying the outstanding balance on the account in June 2017. This month I received an sms informing me to pay R70 be cause I am owning the store an amount of R195. I inquired at the shop they said it was the funeral policy. I have consulted the store several times but nothing has been done. I still receive calls and sms's saying I must pay the money. I have also contacted the Hollard company to cancel the policy but I got no Joy from Ackermans. they keep on asking for money I do not owe them.

Thanks
