Bad attitude from Management

I had visited this establishment on the 06/10/2018 and is most probably the worst service or response from management ever received. The ****tail brought to our table tasted like sewerage water and the "Nachos" was actually potato bake... When sent back to have it replaced, management simply said that they will not replace or refund and that we have no other choice than to pay for the awful drinks and food and if we want a replacement, it will be an additional order and we will still pay for the food and drinks that we're not satisfied with. Terrible place, wont be going back, I hope their business close down as they portray nothing positive in their response or interactions with their customers.
