DUMA TRAVEL VOUCHERS WORTHLESS

We at Hemingways Guest House, KWT, have been dealing with Duma for some time. They stopped paying us from March 2017. Their outstanding account with us now amounts to R25,430.00. We called and our query was just passed on to the next and the next and the next until the last person just disconnected our call. Previous to this we were told to resend statements and invoices which were done on 05/04/2017, 19/04/2017, 20/04/2017, etc. and the last on 02/10/2017.

I am sorry to say to all Guest Houses and other establishments used by them, think twice before accepting vouchers from Duma Travel.
