CURRY UP IS CURRY DOWN

On the 22nd of October i bought a meal (mutton biriyani) the meal was soggy and the rice was overcooked literally porridge , i had tried laying numerous complaints to get a refund but couldn't I then reached out to a gentleman by the name of Alex who is said to be the manager , upon sending him the evidence that the meal was just horrible and not to pleasing to my appetite, after a day or 2 he replied and said that they would be happy to assist with a voucher, i then requested for the voucher or meal as promised only to be told that i have to collect the meal myself , WHY ?????? when i paid delivery in that horrible order i received . now when i am disputing this and want my money back I am being told that head office wont allow ??????????? why do people not deliver the level of service that people pay for , at the end of the day i paid for that meal , and it was not worth eating , curry up is really losing its touch and this is not the first time that i am complaining about their food they need to do better , BREYANI IS AN AUTHENTIC INDIAN DISH THAT IS COOKED TO PERFECTION , I CANT UNDERSTAND HOW THEY ARE AN INDIAN RESTRAURANT THAT FAILS TO COOK INDIAN dishes.
