Poor Customer Service

I bought 2 Johnny Walker Black and two water freebies on Saturday. The carrier plastic bag tore outside the store and one bottle broke. I went to the store to lodge a complaint and get a refund or swap with an opened head of the bottle.This was the worst ordeal that I have encountered throughout my life after being a customer with them for over 40years.I spoke to the store manager , who told me that I was supposed to bring to the store all the damaged bottles to the store.I complained about the quality of the carrier bag. The store manager told me to write a complaint to the plastic carrier bag.His attitude was so condescending and told me that if the plastic broke I the store , they were going to replace the item. And he said it happens regularly.. My take is that the plastic carrier bag is not durable. He promised me to comeback to me on Monday 22 and didn’t do that. I am a pensioner and cannot afford to be treated in this manner
