The Professional Couriers — consignment not traceable

I had booked to send envelope from professional courier from bengaluru sarakki branch to hyderabad on 21st feb 2020. The consignment number is not traceable in their site and when i called cc they asked me to visit booking branch. I had visited the branch couple of times and each time they tell some story and not serious about my compliant. This seems to be worst company as senior members email id is not available in net. I could not book complaint online as their system gives "something went wrong error".
