Don't buy anything from PEP Lakeside Mall

I bought 2 pairs of earphones on the 26th of January at Pep lakeside mall and when I brought them home, one of the earphones the audio was low and the quality was like they were underwater and the other pair had to be repeatedly twisted and adjusted at the port in order for the audio to play properly, the very next day on the 27th of January, I tried to get them returned or exchanged, and they refused to return them and told me that the earphones were working fine and that they only return earphones when they are faulty. Why would I buy earphones, use them for less than one day and then return them the next day and lie and say they are faulty when they are not? If I wanted to return them for no reason I would have still had the right to because I bought them the previous day, what kind of store policy does PEP have that doesn’t allow you to return something you bought the previous day? unless you know you're selling faulty stuff and refuse to give people their money back. In this case though the earphones were actually faulty and they may as well have said that I was lying and refused to take them back. I don't have the time to waste by lying when I had every right to return them the next day, even if they were not faulty, VERY DISAPPOINTED with the service at PEP lakeside mall. When I emailed them they asked ME for their store number so I had to look it up and then they told me that the Area manager would deal with it. A week or so later I don't hear anything from them so email them to ask for feedback. They email me back and say that they called me numerous times but I didn't pick up so they closed the ticket. I have no idea when this happened, because I didn't receive any calls. Why would I go through the trouble of asking them for feedback via email? and at the very least why didn't they sms or email me immediately to tell me that they are trying to call me but can't get hold of me. Instead they waited for me to contact them first and ask them what's going on and to cover up the fact that they didn't do anything they're trying to turn this on me. Bad customer service and Bad service all around, PEP has a long way to go.
