Bad service

Please help

I'm so disgusted by the type of service I received from the Khayelitsha Branch with the Manager Eric. Last week Tuesday (07/11/2017 if I'm not mistaken) my fiance took back the car battery that we bought from the store less than 4 months ago as it was not working properly and kept on being flat everyday. We took it back to the store with the receipt and they took it and made a copy of the receipt and said they will get back to us in 2 days.

When I called the Friday we were told they took it to factory to have it checked and we will get feedback in 2-3 days. Today I called and asked for the feedback as no one got back to us and was told I should wait as they can only call us once they hear something from the factory.

My question was should the factory not get back to you in another week or for the rest of the year does that mean I can get my battery then? Eric sounded irritated and said he will not answer that and we should wait.

This is not fair as our car is just standing at home as we can not drive it because we now don't have a battery. We even struggle to take our 3yr old to school because we don't have a car.

I buy most of the things for my car at Autozone when it needs to be fixed as I believed that you have quality products and this is the first time had to take something back to the shop and I'm so disappointed with the type of service we got.

Someone please assist as this has inconvenienced us for about a week now.
