Bad customer service - Consumer Complaint for PEP STORES

Good day,I bought a phone at Pep cell (Mabopane square branch) in November, and in December the phone had a speaker problem, and I tried to take it back at the shop and one of your staff members told me to get the memory card ( of which I was surprised how the memory card can affect the phones performance)..., Fine I bought the memory card, the phone still have me the problem with the speaker and it couldn't download some apps...fine, until in January I insisted that they take it for repairs cause I run a business and it was and still is till now difficult to run my business without a phone... problem is the phone is not back till now and I've been to your shop more than six times to find out what the delay is all about and each time I go there, I'm being told that it's not yet back from repairs, and nobody is taking efforts to find out what the delay is all about. On Thursday the 4th of March I found a lady by the name of Imma, and she told me that she will find-out what's the delay and come back to me and she never did, fine on Friday I went there again and she told me that she forgot and I should call her on Monday to remind her. I mean really I bought that phone with my hard earned money and this is the treatment that I get from Pep store after getting my money, it's like I'm nothing now ..and when I ask her to refund me so that I can take my money where I'm valued, she tells me that there's no refund and I can lodge a complaint, she will wait for the reginal manager to give her instructions as to what she must do...I mean how can you put an incompetent person on management who is not even able to resolve a mear complaint. ..with due respect, I'm just pissed off with this whole ordeal of being send from pillar to post, so kindly liaise with her and give her instructions to refund me since she is waiting for her regional manager of which I don't know how cause she is the one who should be communicating with him)her with this matter. Please I really appreciate it if you could give me my money back, I'm done with Pep store and it's incompetent staff which doesn't value their customers...0826782633
