Indian Oil Corporation [IOC] — delivery persons irresponsible reply

Address:

Yapral, 500087

I had booked my refill on 9th july 2019 and i called the delivery person of my area yapral whose name is suresh ([protected]) on 15th jul, he said he wont be coming that side today so tomorrow only possible. Then on 16th i called him he said yes i received your booking but today not possible tomorrow surely i will get bcz i am not coming that side. On 17th he says by evening i will try to get ir delivered to you orelse tomorrow i will deliver and today is 18th and when i called he says your booking is not there slip didnt come so you please speak to office executives and when i called the executive mr. Kumar ([protected]) he says your slip is not generated but we will tey to send it soon.
What is happening?? Are customers fool and having no work?? Delivery person's job is to deliver but he says he is not coming that side. I wont stop after posting here and i will surely raise this issue.
