BAD SERVICE BY MOKGADI (PAT) ROCHESTER

Last year December, i bought a dining room suite from them. My sales person was Mokgadi (Pat) based in festival mall. I first walked in and asked about their products, she then advise the 6 and 12months 0% interest, i did not qualify for i then told her i would bring my nephew to do it on my behalf. We came in store we still emphasised the 0 interest on 6 months. My nephew got approved for both 6 and 12 months. The only reason we did not take 6 months its because of the high instalments and higher deposit, so we opted for 12 months still 0 interest fee. We went to one of their stores to pay the R5500 deposit. Now recently i try make contact with her to find out the balance as we want to settle the accounts, to my surprise head office tell me of a ridiculous amount. I then now decided to call Pat from the festival mall branch to find out why my balance is higher, she then asked me to bring my contract which now she shows me interest on it. When we took this contract we told her so well that we dont want interest only on saturday she told me it has interest which we never agreed on. on our way from Bradlows i then ask her to call head office and explain this issue that we now have. she told me in my face that she is not gonna do that. she said call them and say what? she said that why she doesnt want to do finance sales she prefer cash because she has this things...Im sure if its her store she is allowed to say that but in this instance i am a customer and im also contributing in her salary. she shouted and decided to go sit down without resolving the matter, her manager tried but it was too late as i was already furious. I have recording of the matter, what ****ed me is that she remembers everything that was discussed including the fact that will settle the account. but she doesn't remember not telling me about the interest. at the matter of fact that was very important as we stipulated that we want nothing to do with interest. worse she was chewing gum and making noise if you have footage i suggest you go watch it and come tell me is that the service one must experience as a paying customer. Two things that must happen is that you re do my contract with you or you reverse all the money paid from my end and take your dining room suite and we look in different directions because i am not gonna be held responsible for what she decided on our behalf. i would like this matter to be resolves soonest.
