Amazon India — Shortcoming of items in order No. #[protected] dated June 16, 2021.

I placed an order No #[protected] dated June16, 2021 on Amazon India. Order was delivered to me on June17, 2021. I opened the packet of order on
June 19, 2021 due to Covid. In the opened packet I found two items short as below:
1- ROBODO REL_9 Johnson Geared Motor 300 RPM 12 Volt -01 No.
2- Robotbanao Mg 995 Metal Gear High Torque Servo Motor Black -01 No.
The Cutomer care personnel was informed through chat about this shortcoming subsequently but till date neither short items have been received nor any refund as well as no intimation from Amazon India. Their customer care number [protected] is also not working. No complaint email address has been provided by the Amazon on their website so I am helpless and totally unable to contact the Amazon India customer care.
