Builders Warehouse lack of care and follow up

on 19 June I bought a new Ryobi generator for R8999. On 08July2019 I noticed that the Lithium battery had shrunk. I immediately took the battery to Builders Warehouse in Protea Glen. I was informed that the Ryobi sale agent would come and collect it later that day. I returned the following day and Xolani informed me that Slindile had not come due to some work constraints. I gave them time and upon my return on 15July2019. Nothing had happened and I asked to speak to the mananger(Bongani) who assured that he would give me a call about any developments. I went back to the outlet again on Saturday 20July2019 and no one knew anything about my case. Slindile was then called and he said he could only look into it on Monday. I requested to speak to him and to my regret. I encountered an imbecile who barely knows how conduct a simple customer related etiquette. He spoke to me like a like i was pouting child throwing a senseless tantrum. Township organisations fail merely due to lack of respect for customers. Black on black customer service sucks and worse I cannot be refunded for I am refused even such.
