Misled into a funeral policy

On the 22nd of August 2023 a gentleman called me to upgrade my funeral policy. I was paying about R200 and was given more benefits my premium was increased to over R300. I was informed the policy before will be cancelled and replaced with this one. Meaning I will be paying R319.36 only with no waiting period. We agreed this new premium will go off September. However I have been debited twice in August and September. On both months I was debited R200 and R319.36, this was not the agreement and rather pathetic service to be misled like that. Please can I have funds refunded and put back to my old cover. In addition, stop calling me for upgrading policies, I will call in myself. Please resolve this matter ASAP.
