Terrible Attitude towards customer

Sent an email requesting a front disk for a motorbike. During a trip from Zambia to Southafrica went to collect the disk. Upon return to Zambia a few days later, I tried to fit the disk and discovered that it was for the rear and in fact not the front. <br> <br> Upon returning to southafrica on one of my trips I decided to take the disk with to try and find out if it was at all possible to return the disk. I explained the situation to the gentleman at the counter and he told me that it cannot be changed because it was beyond the 7 days. I said ok fine but then I just wanted to know if I can not change it on the basis that it was the stores fault. He then raised his voice telling me that I should have called and asked them to make plan. I told him I'm in a far off country and didn't know when I would be coming back. He continued to talk over me with a raised tone s<br> As he repeated what he had explained.
