No communication

I made an online purchase through the MAKRO store. I purchased an Ellies 12 V 102 Amp Royal Deep Cycle Battery. I collected it from MAKRO Riversands on the 2nd of July. I had not set it up nor used it and a week later the 8th of July it started leaking fluid from the battery. The battery caused damaged to the back of the car and now the car is in for repairs. I have tried copious times to contact MAKRO to have it replaced or get a refund. I logged a return request to which I received an email regarding my issue. MAKRO had tried to call me, but I was in a lesson teaching and could not take the call. I returned the call and was put on hold various times whilst they tried to find the right consultant to deal with my problem. No one at MAKRO Riversands was able to tend to my problem, I had an employee even hang up on me. I was told the only solution is to return it to the store or arrange a collection which will be charged, even though the issue is not my problem. I have tried to arrange a collection, yet I have not heard back. I have tried calling and emailing MAKRO. I would rather return it to my nearest MAKRO and get a refund.

I have been trying to get in touch and I am desperately needing this problem resolved
