Well, someone on Facebook suggested I see if there's any drop down boxes on Internet banking and pay it.
They also said why should I pay the solicitor when it's Digiturk that have employed him.
So, went online and there were 2 payments showing, total 64 tl. One for the whole of Feb, and a part of March, which would tally as although contract started in feb they didnt collect first payment til mid march. So have paid, and had receipts emailed to me.
Have just written in my best Turkish to explain why I didn't pay before to their solicitor and will send receipts recorded delivery.
Fingers crossed it will be the end of it. But not holding my breath.
Insallah.
