Bad product and bad service

I ordered a waterfiltration vacuumcleaner online on the 22nd of February. They state that you will receive the product in3-5 working days. I phoned them after a week on the Friday wich was 7 days to ask what is happening. The guy Victor said he will find out from the couriers and phone me back. He never phoned back. I phoned again on the monday and he said he will phone back. He phoned back to tell me there is no stock, they will have stock on the Wednesday 7 March an he will send it overnight an I will receive it on Thursday. I received it only on Friday after 15:00. The Saturday morning 9 March I assembled the vacuum cleaner, read through booklet and put the right amount of water in. I switched it on and saw the water spraying out. The I looked in the booklet again and my husband said everything is assembled correctly. Where the water is coming out it blows out. I then send an email to let them know I want to return the product, because I am not happy. The monday I received an email saying I must assemble it again and send photographs of how I 've done it, because I assembled it wrong. I the phoned Victor and he said the same to me over the phone. I told him that it is already back packed in original package and sealed I am not going to do that, so he said he will phone me back he is going to phone the warehouse and ask them to phone me. I never till today the 14thnever received any calls. In the return policy it states if you not happy with product you must send it back in 30 days. Nowhere it states that you must send photos of assembling product before you ask for a refund. The service is very poor as well as the product. Please refund me. I already bought a much better vacuum cleaner with a 2 year guarentee. I could not wait longer to live without a vacuum cleaner. Kind Regards Reta Roux
