Unfair Warranty Claim and Customer service

I took my vehicle's battery back to Willard Gezina because it wasn't keep it's charge because it was under warranty to check what's wrong. The sales consultant,Ruben asked me what's wrong with battery. I told him that I didn't drive my vehicle for two weeks and he tested the battery and told me that it needed to be charged. I told him to charge it and I'll pay for it and I come collect it on Monday. I handed it in on Friday,2026-07-17. On Monday I went to collect my battery and the same sales consultant, Ruben told me that the battery wasn't hold its charg,Voltage and because I didn't drive my vehicle for two weeks my battery cannot be replace. He told me that I was supposed to book my battery in for the two weeks that I wasn't driving my vehicle for charging my batteryat Willard. I'm very unhappy with Willard's customer service. All my vehicle's is using Willard and Sabat batteries. I'll never use The Willard battery Group's batteries in my vehicles ever again.
