Unhappy and disappointed customer

When the salesperson contacted me to tell me I qualify for credit I was hesitate at 1st and not interested but I eventually gave in. I was heavily pregnant then as I had told the salesperson whom her identity I will not reveal but anyway I went it to the store to finalize my registration then my 1st dissatisfaction with the service occurred. I was told I need to pay a deposit for the items I took and when she was questioned she said she assumed I was aware that a deposit is required was so mad how can she assume instead of telling me so because I had no deposit I had to go back home whereby I had wasted my time and petrol. Then after some time she contacted me again and told me that the deposit is no longer required and I told her I had just given birth so I can't come into the store and she told me that the manager will come to me to sign and explain documents which I was impressed. The 1st time I went into the store and chose the bed she suggested I told her I don't want the masterguard service and on the 2nd encounter I chose a different bed from the catalogue I had seen online the bed was R5000 and she convinced me to take the bed I had previously seen in store telling me it's on special worth R5, 500 and I decided that I can handle the R500 difference and chose that bed she had suggested again. Okay the manager came and explained the payment terms and insurance etc and I agreed. Same day the bed and couch were delivered. 2nd problem occurred the couch was not the exact color I wanted I told her and I told her she said she will send me pictures of other colors they have which she did not and I decided that it's okay I will settle with the given color. After a few days I was looking at the documents I was given and realized I was charged R300 for the masterguard service which I clearly told her I don't want and did not get and was also charged R6000 for the bed instead of R5, 500 I confronted again and she told me that she was off and that means when they were processing my documents the bed had already increased and the masterguard fee has been charged and cannot be reversed was so mad but contained myself then I was making my bed and noticed a defect on the bed and I notified her about the defect and requested for a bed exchange for the same price but different brand and she told me exchanges take place within 7days

So I am a very unhappy customer because I feel like this salesperson failed to offer me good service and she misleaded me throughout the purchase and now I must pay for goods I am no completely satisfied with which is unfair really. This bed is uncomfortable and more than the price I told it was worth and now they can't exchange it for me for a brand I desire and bed that will satisfy me, I am forced to accept the masterguard service I don't want and stuck with a couch that the color I don't like. I will no longer make purchase at this store ever again the salesperson is misleading and not completely truthful I am so mad and disappointed
