Bharat Sanchar Nigam [BSNL] — Paid my landline/broadband bill twice

Sir,
The bill receipt that usually comes by 17th or 18th of every month came late this month (around 23rd or 24th) but since i pay the bill online the receipt itself was not any problem, so i paid the bill well before due date, but when the bill did come my brother filled it again and it was submitted twice. I'd like you to look into the matter and reimburse me the sum as soon as possible, I've attached both the paid receipts with this note.
