B. E. S. T. Undertaking — payment of bills

Address:

Mumbai City, Maharashtra, 400 016

On 5th sept. 2018 i had put in your drop box at mahim best depot (Because of big queue so unable to speak to your man at the counter) the completed mandate form duly signed by my bank - union bank of india, mahim (West) for ecs payments of my bills - consumer no.[protected]*5, together with a xerox copy of a blank cheque.
So far i have not received any confirmation that it has been registered. I paid the sept. Bill by cash at the depot, and at the time your man told me the form must have been sent to your dadar office. I have now received a message on my phone about my october bill.
Please confirm that the bill amount will be collected from my a/c as per the mandate.
