E20 issue

Ever since E20 fuel was introduced, my car's mileage has dropped drastically from around 16 km/l to just 9–10 km/l. I am extremely worried because I can no longer afford the fuel expenses.
Earlier, my monthly petrol cost used to be around ₹6,000–₹8,000, but after switching to E20 fuel, it has increased to ₹12,000–₹14,000. Because of this, my car now stays parked at home for almost three days a week, as I simply cannot afford to drive it regularly.
I drive very carefully and always try to maximize fuel efficiency, but even then, the mileage never goes beyond 10 km/l. My car's engine is officially E20-compatible, so this level of mileage loss doesn't make sense.
I have visited the Tata service center many times regarding this issue, but unfortunately, it has still not been resolved. I am very frustrated and don't know what to do anymore.
