Hello Kanokporn and Wasawat,
Wasawat, it was nice to speak to you this morning, thank you for your time and for clarifying this for me.
We will make a transfer of THB 3,500 to your account today - it is likely to take a couple of days for the funds to reach you from our bank, but we will send the funds as swiftly as possible. We have increased the amount slightly from your figure below, to insure that enough funds are received to cover any interest cost. We can then reconcile any over-payment in next month’s WHT return as required.
Given that this is a small amount and the fact that we would have hoped that your calculations would capture all payments, particularly those made to RSM, we would appreciate if could pay this amount as soon as possible for us to the authorities, in order to avoid there being any further charges on the account.
