Not impressed with Renew-It!!

After my vehicle was fully repaired in a speedy time, which i am thankful for, my car's battery came back flat and almost dead. I had to pay for a new one to be installed to be able to get to and from work, i did notify Renew-It Greenstone. I was notified that the charges of my battery would be refunded. It being a tough month due to all courtesy car expenses and to get lifts to and from work when my car was still in repairs, i did not budget for that R1000's battery charges. I still have not received my refund and every time i follow up, i get a response that they're looking into it and will get back to me. I know it's not much but with that money out of my account one debit order could not go through, so my debt score is going to be affected. So disappointed with this.
