Bharat Gas — charging more money while delivering the cylinder

Address:

500089

Hi sir, i have booked a cylinder from ebharat gas through online on 27 feb 2019. My ebharat gas connection is located at 8-1-299/1/a/10, madhura hills, shaikpet opp. President function hall, hyderabad, telangana 500008. The cylinder was delivered after 9 days and they have charged more rs-80/- extra while delivered. This is the second time they have chared more. When i asked them they are simply saying the gas cost got increased. If they deliver cylinder within 2 to 3days the cost will be same. But they are delivering after 7 to days because of collecting more money. Please takcare of this.
