Well after people's comments above I checked my TEB account and it appears that Muski are now taking direct payments from TEB or better still the direct debit. So I have set up a direct debit on the internet bank, and will keep a close eye on the next water bill for correct payment from bank.
Mind you why they did not tell me that they had started or rather reintroduced payment by direct debit for Fethiye bill payers, either on their website when I have been making payments on it or even e-mail, as they have mine!! Very poor, but only as expected suppose.
Thanks for the steer.
