Mahanagar Gas — my request for disconnection is being delayed & unnecessary bills being raised

Sir,
In my earlier mails, i requested mgl to cancel this connection & asked to simply inform me 'full & final' payment so that disconnection becomes hassle-free.in response to this, mgl informed me the 'full & final' amount.
I remitted 'full & final amount' immediately & was expecting mgl's action of disconnection.
But no action has been taken. No information on it & mgl has simply continued to raise bills!
This will be an unending affair!!!
Does mgl not have coordination at their end? Instructions to stop billing should have gone to billing department after my full & final payment! Also instruction should have gone to the operational team to disconnect with advice to me.
I do not wish to pay charges or bills any further under these circumstances.
Will you please instruct for disconnect the supply asap.

Thanks,
