Philips India — HL7707 -- Mixer grinder Jars not grinding even coconut

I have buy the HL7707/00 mixer grinder on 15.03.2022
from one day, i have faced lot of problem from this mixer jars not even crush the coconut piece . juicer jar not crushes even pomegranate juice, fails to filter the juice . total waste of buying this mixer grinder and waste of money .

alot time i called local service center ( TRICHY, TamilNadu-620001). After a month they visit my home and replace blade for 0.5L jar . i asked that service person to change the blade for juicer jar and 1.5L jar . he told me replacement within a week ; but after a month i make a call to that service person, he respond not available of blade . i ask him to replace the jars . on 04.07.2022 i went to service center, service person show to me new jars which is not suit this mixer grinder ; he show some other mixer jars to me for replace. i left from the service center without any replace .

i need solution for this problem . replace jars with same models ..
