unfairly treated

In september i placed order of gabariella 5pc towel set saying buy one get one free and only received one set only. I call homechoice they said they will deliver it after 14days, i received massage saying i can go to post office to collect my order there was nothing there i called homechoice again and they said they will find out what happen, i called them again and they said i can go to the postoffice its there, there was nothing again, call them and told me that they will find out what happened till today nobody called me from homechoicem.in october another order of michelle 5pc duvet inner buy one get one free same problem.so disappointing to see such a big company with such bad service
