Air India — Refund not being paid back

Address:

Mumbai India

All this process of cancellation which to date has taken 11 months I have been informed that cancellation fee is £300 for the two o[censored]s, also that both our tickets would be refunded by air India. They are informing me that the refund has been sent, I have received the equivalent of one ticket, although when requested the transactions ID the amounts sent and date I have been informed that they are not allowed to send via E mail? I find this strange as the booking and tickets are sent by e mail. Bank have requested these numbers to search their system. I have worked out that I am £800 short of a refund. I was told by customer care there was two amounts to be refunded both over £709 plus each, all of a sudden this is being denied to be refunded. Apparently this is a very common occurrence for Air India!
