IFB Industries — No action taken after multiple complaints

I have a washing machine serena sx 5.5, i have an AMC against this product.

I have created my first ticket on 13August, as my machine tub is bumping into the shell, a technician guy came to my residence and told me that the shockers needs to be replaced and he was having that parts but told me that he doesn't have a key to open the bolts, further second day another guy came he told me the shocker is not compatible, the third day another guy came stating i don't have the screwdriver to open that particular bolts(screws), further they called me saying "sir i will come tomorrow. No body came

I further filed another ticket "[protected]" on 19 August but the technicians called me for two days saying sir we will come tomorrow, but until now my issue is not resolved, machine's tub bumps so horribly that it might cause an big accident some day.
majorly these technicians always suggest not to take amc instead call them directly get the repair done privately.

I just want a final solution now whether the issue will be resolved or the company ignores an old customer or do i need to switch the brand?
