Mahindra And Mahindra — Poor service in service centre in the name o[censored]navailability of spare parts required

Address:

Salasar Mahindra Service Centre, located at Kolshet road, Dhokali, Thene (west

I am owning a Mahindra KUV-100 bearing Registration No. MH-46-BA- 0479. On 22.08.2021, I came to know that the main pipe/tube of my vehicle which carried petrol from petrol tank to engine got leaked. I then visited to the authorized mahindra service centre named Salasar Mahindra Service Centre, located at Kolshet road, Dhokali, Thene (west). I have been communicated that the necessary part (bearing part No. 1001CAA15820N) is not readily available. The same would take two to three days. As my vehicle was not able to be taken, I left my vehicle to the service centre. On follow up, everyday I have been communicated that the same may arrive by tomorrow. And after five days i.e. today, I have been communicated that it was a back order and they are unable to say till when the required part will be available.
Its really disheartening that such a world famous company provides this kind of poor service to its customers. It seems that there is no value of other people's time. Is it justified at all that just for changing a small part, after 5 days a service centre says that they are not even aware that when they can get the part. How many days I am supposed to keep my vehicle standing at the service centre like this??
It is quiet obvious that how unavailability of a mode of transportation, may impact a day to day life in a place like Mumbai. I am working as an Income Tax Officer and It is simply making me difficult to attend my office daily. Who will be responsible for the inconvenience caused because of this?? How many more days I need to wait to get my car back?? Or finally I should visit consumer forum to get the answers and the service which is required to be done by the so called mahindra service centre.
