Dear Richard Anderson,
When I paid for my for my phone bill yesterday via online banking, I erroneously entered $1520 instead of $152 which is the actual amount due. In this regard, I kindly request that the excess payment be reimbursed to me immediately. You can send me a check or transfer the amount to my bank account from which the payment was previously debited. Thank you.
Sincerely,
Dierdre
