Complain

I went to Jet Campus Square on the 07/12/2017 to exchanged stuff that was bought as a gift. I had the cash slip with me and a guy in the store assisted me with the exchange. He assisted very well and was very friendly. On the 13/12/2017 i went back to the store to exchange another pair of shoes for a bigger size. I spoke to the cashier at the store and she told me she cannot assist me without the card number of the purchaser. I told her but the guy assist me without a card number and i was informed that the guy went for a hearing because of that. I left the store got the card number went back the next day. When i got to the store with the card number i spend my whole lunch time in there just to be told they cannot help me i must go back to the store where it was purchase I am a very unhappy client got late to work from my lunch time without any help at the store. I need this issue sorted out as I am not going back to Clear Water Mall where i have a store closer to me.
