United Bulgarian Bank issued the following announcement on June 24.

Dear clients,

The main value for UBB is the provision of quality service.

In this connection, we run a customer satisfaction survey via SMS from the phone number 10800.

After visiting a UBB Banking Branch, you may receive an SMS message asking you to rate your service on a scale of 1 to 10 (where 1 is the lowest and the 10 highest the level of satisfaction).

The survey is entirely at the expense of the Bank and you will not be charged for the replies.

Thank you for participating!

The team of UBB
