No Response after Numeros Visits

If purchased a Zippo Lighter from the srote buy it did not work from day 1, Returned it after a week and they gave me an even worse one. Returned that one and the cashier told me she will give it to the correct person as she is the only one in the store, she tooked my number and the Zippo. They did not give me any receipt of taking my item. Yhey dit not called back so I visited them again after a few days. The same lady was there and told me she did give the Zippo to the right person and will ensure that the person calls me. That was a week ago and I am still awaiting feedback.
