The 10 minute lie!

Came in this morning 09h15 with my sister's Nissan Micra. The car had not driven in a while due to the lockdown and working from home. The battery was dead and the car had to be jump-started by Nissan roadside assist for the third time. As soon as we got the Nissan BB Gezina and stopped the car, it wouldn't start again. Upon further inspection we saw that the 2020 Nissan Micra purchased in Feb 2020 had a battery that dated back to July 2018. It took them just over an hour to decide if they are going to replace the battery under the warranty. We were told they decided to replace the battery at 10h20 and we would need to wait another half an hour. After that we were told to wait 10 more minutes, then another 10 and then again another 10. It is now 11h40 and we were told someone left to get the battery from Silverton, and we would have to wait another 01h30. Knowing that we are in a rush to get back to work, I feel the consultant could have told us to go home and come back when they are done. Or this tell us that it should take about 5 hours to change the battery.
