Refund went wrong

last week on the 3rd I went to Rage to return a pair of boots which was damaged, the service was bad a consultant gave me bad attitude and she was laughing at me, however I was offered a refund and that refund turned out to be another purchase which I only noticed when I got the sms from my bank.<br> <br> Now I was communicating with Wendy and I have to go back to the store for a proper refund for both transaction which was not suppose to happen and When I asked who will pay the extra charges and transportation fees that I incurred due to their staff incompetency , Wendy told me via email that I am laying off on the wrong person cause is the store that made a mistake.<br> <br> I need my refund for both transaction, transport compensation and banking fees compensation.
