Bad Service

I bought a supposedly smart phone @ackermans eastgate where it took me a great 30mins to be assisted by the cellphone consultant. While she drags her feet to the backroom to make my id copy I patiently waited. Received my phone,got all my slips and left the shop. Got home the phone did not meet my expectations at all. I gave it 3 more days and only to be frustrated further. I took the phone back since it was still within the 7days return policy and explained my situation only to be told by the supervisor there is nothing he can do but he will send it back to the supplier and have them check it. 21 days later I am still waiting for a response or an update from them. I went to the store on Friday only to be told the phone is not back. What's frustrating is that i am not contacted by Ackermans to let me know what's happening and with a phone that they claimed "nothing is wrong " with it then surely it was suppose to be back by now. I want my refund and I will go buy a new phone where as a customer,I will matter. The supervisor Rhulani and the consultant Celiwe did not seem to care at all when I raised my concerns. They made write my details on a piece of paper and told me to leave the phone with them. Surely I was suppose to be getting a ref number or see where this is recorded....I have had it and want my money back.
