Bottomless boiling water, not so much loose leaf tea.

I ordered the "bottomless brewed tea leaves" on 14 July 2018 at 14:06 pm from Longbeach Mall Mug n bean. I ordered the "green tea" flavour. This tea flavour was disappointing to say the leaste, true this may be a subjective expectation. However when I asked my waitress if I can please change the flavour to permit leaves, she rep**** that I will be charged twice. The manager said I could NOT chose a different tea flavour under the bottomless tea. Then I pose this question to mug n bean and there marketing, why are you setting up the expectation of "bottomless loose leafe tea" when you are actually in reality sellling bottomless "boiling water". This service encounter was a failure and and the service recovery was also short by the staff in the restaurant. To all other consumers, do not order this false promise.
