Easy for you, frustrating for me

One of the easiest sales a salesman could hope for, but such a frustration to get after sales support. Within a month of purchasing my car the battery died and needed to be replaced. Contacted the salesman who discussed it and got approval from his manager to replace the battery at their cost. With 2 months of follow ups and chasing i am still waiting for the battery to be replaced, having to be jump started almost every day, and even worse their system is always 'problematic' to get me my service and maintenance documents resulting in the car being overdue for a service and without it I cannot take it to a workshop near me.
