Indigo Indian Food don't take care of the customers

Their food is delicious, if you actually receive it, as it's supposed to be. I always order the Vegetarian Briyani. Couple of months ago I received it without Dahl (not the first time) and instead received a long hair in my food. After boycotting them for litterly months, my taste buds just couldn't take it any longer. Today I order my favorite again. Just to receive it without Dahl AGAIN. All they say is they can't get hold of Head office (where the hell are they? No care in the world) & a sorry. This is unacceptable!! NEVER AGAIN. ***** my taste buds, I'll find another Indian take away that doesn't make me so HANGRY. I'm done.
