Poor customer service

I went to the hub in wonderpark their manager and staff they don't have customer service they gossip about customers and laugh customers I have made laybye yesterday to find out the clothes I bought as I took 11-12 but the person I should bought they told me in the morning I have to take 9-10 I went today to asked them to cancel them to exchanged the sizes but they mustn't take penalty because I just need to exchanged the size as if I waited for next week I might fine sizes gone they call the Manager and she explained that it won't be possible unless I took the.laybye Today I told them It won't be possible may be if they can call their regional manager and explain the whole situation will understand they said unfortunately no we need to deduct a certain percentage I said but I need to laybye again as I have said I just need exchanged only sizes so you mean I have to cancel and you took tha percentage and I laybye again It doesn't make sense she said no its a policy I can't changed it I said yes you can't but I think the regional will understand and authorize that it's not like I cancel and I don't buy thevwhole amount was R2800 ibtook deposit for laybye R1000.i decided to canceled and go and do laybye in Woolworths when I go out from the tills when I turn the manager and her team were talking and laughing when I turn around they keep quite that's so.low if you find a manager gossiping with her staff about a customer I don't think I will shop at the hub wonderpark it's a store that I always buy clothing there with cash But today I experienced humiliation as they were laughing at me can you imagine a whole manager with the people reporting to her laughing at the customer who gave the sales it doesn't matter how much the customer brings into the store sales are dropping but still some stores they don't know how to treat customers with respect because they undermine us
