FRUSTRATED CLIENT, PLEASE HELP!!

I'm actually in need of your help. I had purchased some products from cook4life in March 2021 and as the contractual agreement states that I will be debited R500 each month on the 17th starting 17 April 2021. but this agreement was not true, Cook4life debited my account on the 15th R259.75 and again on the 18th of the same month R509.75. this has been happening from March 2021 till September 2021 . basically My account has been debited twice every month different amounts. I contacted Cook4life in September 2021 and queried the debits , eventually I had cancelled my order in September and requested a refund of my money that has been paid to Cook4life. I was informed that my money will be refunded after 60 days which states in the contract and I agreed to the terms. My 60 days has passed and no money received, I contacted them again and was told that I was going to be refunded a portion of my money in the 3rd week of December 2021 and I asked why a portion and not my full amount, I was told they were going to call me the day after and till today no communication was received from Cook4Life. I Need your help as to resolve my problem . PLEASE!!!
