unhappy with service and received a bad attitude

To start with my husband first phone Cash Converters at Gift Acres asked if they can let him know when they receive stock on the complete psp's and we want 2. They took his name and number, after a week or so we hear nothing. We have the money and went there to see if they have stock. The man who helped me showed me to the glass showcase and I couldn't see any even my husband went to see if he can see any but nothing, I told the salesman there's nothing and he came back with 2 wrapped in cling wrap. We checked both black psp's only the one showed a key I told the lady where I need to pay it's not working. I took out a pink memory stick look if that's the problem and put it in still the same. She gave me a white one with no memory stick inside. I check it all fine except the memory stick, I told her there's no stick inside so she said no some have other not thry sell it like that. I asked if I can take the other psp's memory stick and she said no. I leave it and go home it was a long day there. After a week or so I phoned the shop and I spoke to Jackson second in charge ( they told me the manager was on leave and will be back the next week). I explained to him my situation that it's a lot of money we spend there and I want the memory stick of the broken psp. He told me that he will check after a few minutes he told me the psp's been thrown out, I asked why they didn't give me the memory stick when I asked for it and he said he will check for one. We heart nothing from him and went back at the time the manager was there. I spoke to the manager Francious but I start talking and he didn't listen start talking while I try to tell him I want a memory stick. He said the games can't be refunded and a long story. I start to explain again that it's not a refund that I want a memory stick for my girls psp; my boy got one in his but now it's swopping card from one console to the other and it's frustrating. He said you buy it like that and you pay less for one with no card. I told him I paid the same price as the other one. He didn't make any effort to hear or help. He was aggressive from the start. He didn't offer a memory card or to find me one I have to ask if you receive memory stickd what's the cost , he said R25.00 he didn't ask my contact number I have to do all of the thinking for all of them. I feel I paid a price for a full psp with memory stick and till now I didn't receive any help or call. I drove petrol to many places to search for a psp memory stick duo 32mb. I went to Clicks and bought a msd card psid R199.00 and it was wrong. Went to cell fix to find one and still pertol and time. This is the worst manager and staff I worked with. I want a memory stick for the psp console I paid for and I have the receipt and my details are on their computer system. I want them to give me a memory stick I paid for it. Please I want your help.!!!!!!
