Samsung — Mobile repairing delay

I have been depositing my handset in the service center for 15 day for repair. So they say it took me another 2 months. And the call is not picked up. And when I go to the service center, they say the part is not coming. If amazon parcels can be delivered in 4 to 5 days, how can it take 2 months for Samsung to deliver a part? I am getting only one answer from Samsung company. That's the lockdown. So how is your service center open. What's the point of keeping your service center open for 2 months to make a part available?
