Bad customer service

On the 8th of July I went to forest Hill and buy pampers for my 5 months toddler when I got there I found clicks nappies on the special it was 3 for 2 promo I bought them and I was having the pack that I was still using and I realised after two weeks when I lost the receipt I went the on the 24th asking for exchange they said they can't cz I don't have the receipt, but just imagine 3 full packets of pampers not fitting the baby..Management said I have to bring the receipt and I tried to explain but he just refused at last he said maybe if I used reward card he was going to help me. I really understand that when you return goods you must have proof of purchase but I lost it. I always Recommend Clicks I m a loyal customer I always buy in bulk during month ends cz there is always a big promotion.... I'm not happy I will tell friends and family not to buy at clicks anymore.
