Speedpost — the staff behaved with me badly when inquired about my speed post.

Address: Patna, Bihar, 800021

I booked letter by speed post (Speedpsot tracking no ef[protected]in) on 02/02/2019 through post office located at patna (Vidyut bhawan branch, pin code-800021).
When i checked in the tracking system, i found that consignment not found.
Since this letter was very urgent and was supposed to reach atleast third day.
Non delivery has caused me much metal tension and loss of a great opportunity.
When enquired in local post office (Vidyut bhawan branch, pin code-800021), the staff behaved with me badly. They are denying my consignment but i have the receipt of it.
Nobody responded properly at post office. Please take action
