Ekart — Not receiving call , not calling and quickly hanging up

Yesterday my product came but the courier girl didn't even called and when I called she didn't receive and when received she immediately hanged up without talking and when talked she said she will call and she didn't and when I called again she said she is gone she went and told me I didn't picked up her call like seriously how can someone tolerate that and today also she isn't picking up and when she picks up she doesn't even talk and quickly hangs up idk what to do I'm not even sure I will get my product or not please improve the courier service and customer satisfaction
