Reliance Fresh — Complaint about method of billing

Address:

Edappazhanj, Trivandrum

I am a customer of Reliance Fresh, Edappazhanji, Trivandrum, kerala from its very inception. I have a suggestion for your method of billing, not for a particular branch, but as a whole.
At present fraction a rupee above 50 paise is rounded off to 50 paise, not to the highest whole rupee. Instead of that why can't you round it off to the higher whole rupee or leave that fraction? . My intention is not to get a bill with whole rupee and not with 50 paise. Kindly remember that 50 paise coins are not in circulation.
Today, there was an incident where I received a bill for Rs.50 and 50 paise. I had no coins to pay 50 paise or one rupee. When I paid a 50 Rupee note, the salesman insisted on getting a 10 rupee note from me for a balance of 50 paise, whereas he had no 50 paise coin to pay back Rs9.50. when I met the Store manager he directed the salesman to return me the 10 rupee note, leaving 50 paise.
This kind of situation is to be avoided by issuing bills without faction of a rupee. Please reply.
Thanks.--
