PEP Stores are bad when it comes to service

I just had the most worse customer service from PEP so called customer service head office, Lindokuhle you need to treat your customers good whether PEP Stores has cheap stock to the public don't treat them like trash....all I enquired was about refund policy that is not displayed in store, nor online but she was really ****y and rude to me, I don't accept rudeness as I am a paying customer This is not yhe 1st time I receive such bad service when it comes to refund, they not clear enough , and nothing is published on their receipts nor in store, nor online
