Extremely BAD CUSTOMER EXPERIENCE

I cannot believe the experience I had at Timberland gateway after I went to exchange the Timberland boot for a bigger size and they refused to assist me. The shoe was purchased on Thursday 19 November 2020 by my auntie as a gift for me. Jatheen Vanumi which is a the store manager failed to explain the exchange policy. All I asked for was an exchange of size because of it being to tight. What am I suppose to do with a tight shoe especially after R4300 was spent on the purchase of the shoe. Please assist before I escalate this matter Sandile Ntuli *** ***
