Geeyem Motors — sub: service of my chevrolet beat with registration kl bx 8629 (diesel) car and warranty related to that

As you are aware i have submitted my vehicle for service at your nettoor workshop. The vehicle is already under extended warranty period either it is in terms of kilometers or in terms of the period of warranty. Now after carrying out the work it is seen that you have raised a bill for rs.50, 596/-. It is understood that you have not considered the fact that the vehicle is under warranty. The extended warranty was allowed for the previous services also. You may also note that the vehicle is having manufacturing defect also which you have already pointed many times and which you could not rectify till date and such manufacturing defect is in the knowledge of the company also. Now you are acting against the terms of the warranty and is trying to extract money from me without any basis.
Hence you are requested to set off the bill against your obligation of free service and warranty and release the vehicle accordingly or else i have to take further action in the matter.
