Indian Oil Corporation — Huge delay in refill delivery nd highly unethicl behaviour of the gency staff

We are using indane gas connection through the agency m / s anand gas agencies in palarivttom cochin. The last booking of lpg refill was made on 11. 05. 2015. On enquiry it was informed that the delivery would be made after 11. 06. 2015. But we did not get the refill till 15. 06. 2015. When contacted over phone the agency intimated that the refill has already been billed and the supplier would deliver the same soon. But we did not get the refill on 16th or 17th. Though tried over phone several times the agency had not been attending the phone. When talked on 19th morning they told that the delivery will be made on the next day ie, saturday. When contacted on saturday (Today) , the reply of the agency was astonishing. They have no supplier today!!!. They further intimated that the billed invoice was also cancelled and supply will be made monday next.

The agency lacks credibility and the behaviour of the staff is highly unethical and impolite. Suspect that they are selling the billed refills to some other persons accepting bribe. It is learnt that the cutomers of this agency have lot of similar complaints.
Pl look into the matter and do the needful argently to get my refill on monday (22. 06. 2015) at nay cost.
