Vodacom store potchefstroom(Shop 47)

My Fiance took out a contract in January 2016 for a Sony xperia Z5 where she was told she can choose a free gift. On selecting the free gift there was told there is no stock on that gift and that they would call us in 2 weeks to come and collect so we left it and waited for them to call us with no call for 2 months. On the 09 of march 2016 we went to the store to go and ask what is happening just so that we know about it. First we stood in a long Que as sales persons where rather chatting to there buddies than helping clients and to make it better only 2 sales persons on floor to help while other one went out with his friend. On coming back he eventually helped us, where when we tried to explain about the gift, he kept on interrupting us and telling us the lady that helped us that day is not here and he cant help us and that it is not his problem , The more we tried to explain to him that in here absences he has to take her responsibilities the more he interrupted us. So who wouldn't get mad in this situation. And now they come with a story that they told us to bring the slip not once was this said to us. It is not about the free gift but the utter bad service we got
