Pathetic Customer service

I purchased a Flat iron on 24 December 2017 for R 399.00 but with the mad Christmas shopping rush I lost my receipt I went back to the store to ask for a reprint as the flat iron has a 12 month guarantee and without the receipt I would not be able to take it back in future should it become faulty. I have been given the run around thrice already .I was told that they are unable to assist me as i need the exact time when it was purchased . I gave an estimated time but that was not good enough. I`m disgusted with the pathetic answers that I’ve been given .I understand that it will be time consuming but CLICKS ZEVENWACHT did not even ATTEMPT to assist me . They clearly don`t know the meaning of customer service
