I had a track in your below mail, seems to me that the payment should be effected in July, right ?And you only started chase the case on 20th Nov. and today it is 13 Dec. --- it is hard to ask our bank to check a record without any bank referenceOr bank slip to show the date and transaction route etc.So, pls arrange to send a Credit Note and ask them to rearrange it immdly, you may change the bank to HSBC.
