Extremely Bad Service - Pep Retail Stores

It seems by the looks of it that PEP does not even bother about bad reviews been written about tgem, looking at all the bad reviews and no reply from the store itself. Businesses like these should get shut down because of bad customer relations. Anyway, I bought 2 x Stylo Saturn cell phones on the weekend of the 15th. I have not even used mine when I realized the bad performance of the phone when my hubby started liading his apps. The phones are extremely slow, not performing to our needs, and when we returned it on monday to the store, they refused to exchange it for a more expensive phone like a Samsung. Firtsly, the lady told me no exchanges on phones unless they are faulty, how is she going to sell a 2nd hand phone. Seriously, the phones arent even being used due to poor and slow performance. Secondky, how stupid can you be not to want to exchange them for a more expensive phone, and make the customer happy. What is more important, the fact that you have a happy customer or someone eho id going to badmouth your store after this? I want a refund, or at least be able to exchange the phones for something better like a Samsung. This was a total waste of R1800 for 2 Stylo Saturn phones that are now just lying in my cupboard. I hope Pep reads this, and replies. I have logged a complaint on Monday, 17th March on your website, and to date, NO ONE from Pep has contacted me. Utter bad customer service!!! You just dont care about customer service.
