Eureka Forbes — Worst service - purchase amc on 6 oct but still no visit

Address: Titwala

I have purchased AMC online by paying Rs. 4177/- on 6 Oct, 24 for product Aquaguard Enhance RO+UV+MTDS but still Today 24 Oct, 24 no one visited despite of several calls to customer care.
They daily register complaint and gave assurance for resolving issue on high priority but still no one visited.
Even I spoken with service center they stating that Filter KIT stock not available. On 21 oct, 24 I was informed that kit is available and engineer would visit on 22 Oct, 24.However no one has come and they not responding the calls.
I think Eureka Forbes teams not serious about the service. If stock not available then why sell the product ?
And AMC should be applicable after the installation.
