MAXIBAT/MUTLU Batteries - Stay Away!!!

I bought a battery in January from AHK, Lansdowne, Cape Town. When I enquired about a replacement car (616) battery, they said they got various makes and they all similar. The cheapest at the time was MAXIBAT / Mutlu Battery. I also asked about the warranty process and the salesman told me that should I experience any issues with the battery, I can just return it and they will provide a loan battery while MUTLU (MAXIBAT/MUTLU Agents in Durbanville) inspect the battery. About 4 months later, the battery started giving issues where it just couldn't start the car if the car stood for one or two days. I even thought maybe the car is draining the battery. After taking the car to the auto-electrician, he inspected the car. They auto found not problem on the car and said the battery is faulty. I have then taken the battery back to AHK and enquired about the loan battery. They said they need to ask MUTLU for a loan battery and the process wasn't as seamless as I was told at the time of the initial purchase. The first battery they gave me was a dead battery and they then said I should pickup the second battery which was even worse and even looked physically damaged and was also dead. For a battery company, couldn't they even check the battery or do they not even care about their customers by wasting my time and causing lots of inconvenience. They then told me that the loan battery was a favour and they don't normally do it. This is contrary to what I was told when I bought the battery. The report said there is nothing wrong with the battery and they just charged it. Two months later the same thing happened with the same response. Another two months later I sent the battery back and the same response, they just charged the battery. This is really frustrating and I will no longer purchase a MAXIBAT/MUTLU and also AHK Motor Spares couldn't even help since I bought the battery from them. The warranty is coming to an end and the experience was really frustrating. A company with such bad business practice shouldn't be in business.
