Big Bazaar / Futurebazaar / Future Retail / Hometown — poor experience high prices and careless staff

I visited today at janakpuri new delhi outlet around 2:30 p.m. and tried to purchase tea, handwash and bread but my experience there was awful and horrible firstly their so called express counter was working extremely slow and wasted lot of my time and when they started my billing to my shock santoor hand wash having 99/- mrp was billed at 189/- and tea having 25/- mrp billed at 28/- I immediately raised the concern but in vain as the billing staff was blank on it, he referred me to customer service who kept announcing the staff from concerned departments but no on cared to turn up I even spoke to a senior person name not know who went to billing counter and then disappeared and after a long wait seeing nothing is going to happen here as every one there was either careless or helpless I left after wasting my hour there.
I am totally disappointed with this inconvenience and horrible experience I had today and will never visit any future group outlet and try to instigate as many as possible to do the same.
