Maharashtra Natural Gas [Mngl] — bill dispute for bp no[protected]

Address:	Pune, Maharashtra, 411046

Dear sir/madam
When i was offered the mngl connection, it stated that the security deposit rs 5000 will divided into 10 monthly installments and rs. 500 will added in you monthly bill towards this. This was clarified with your customer care when 1 st bill was generated. So the 1st bill that was generated was paid accordingly ie. Gas charge + 1st instalment of deposit rs 500.
But when i see the second bill that was generated i see that last bill is shown as arrears and the late pay charges are applied on it.
When contacted the customer care they said that all the bill that was paid last time went into security deposit. So it is showing as arrears now.
Also rs. 500 form fee was paid by check issued in name of mngl so please also rectify that
Can you please rectify the bill. As it is not correctly reflecting the status and is showing the wrong details and unnecessarily creating the dues even after paying bills on time.

Thanks,
