I know quite well brother, having worked in honda and Suzuki dealerships.
The calls you get from dealership are formality calls. The rule to get ur car serviced\inspection every 3 months is to make sure that dealership meets their monthly targets. Pretty sure you dont have a money tree for going to them every 3 months, when ur running is clearly too less.
What you should have done (and what owners usually do) is like you got car in june.. you need to go for first 3 inspections of 1k 5k and 10k at the mentioned time intervals by company, which is 1 month, 3 months and 6 months respectively.. irrespective of your car running km. These 3 inspections are mandatory for future warranty claims, as the company checks record when a claim comes.... After those 3 inspections you need to go as per ur running km i.e. 5k km or 1 yr, whichever comes first (oils these days are good enough to last an year long)..
You are not bound to follow the calls from dealership, as that frequent service\inspection is not required for your car.
Look into your user manual for maintenance schedule\table and follow that only... Replace stuff at intervals mentioned in that table.
