Very disappointed customer

We bought a mop in July from verimark. It worked nicely for a month and then the problems started. At first it is the small white thing that has a magnet in to pull the basket up that keeps on coming out. Then the basket started getting stuck either it doesn't want to go down or when it is down it doesn't want to pull up. You had to do it with your hand which is not how it is suppose to work. We took it back on the 4th of Nov explained all the problem to them at first the lady wanted to give us a refund and then when my husband and I asked for a exchange she gave us another mop. She took the old mop head out of the box and put the old one back. we took the mop home and left. When we got home my husband assembled the mop the way the books says and we started having problems again. With the pressing down of the mop to either rinse or drying out the gears of the basket squeaks. The gears doesn't sound very good at all and the mop head keeps on falling out of the mop itself. We took it back once again yesterday explained the situation and after this being a second time we asked for a refund to go buy something that works. I mean it is R599 spend on something that is a load of **** and doesn't work the way it is suppose to. She lady at first gave us attitude and said she didn't say she will give us the refund. Then she checked and showed us but the head is the problem. But she is the one that took the new head out of the box and gave us the old one back and I thought all the mop head fit on each other because that is what she also said. My husband got very angry firstly because of the attitude she gave us and secondly if we didn't ask for a exchange the first time we would have gotten our hard worked money back as R599 doesn't grow on trees. Lodged a complained at the head office through facebook and all they tell me is to take the mop back to the store so that the shop can assembly the mop for me in the right manner because I might have made a mistake in assembling the mop. When I asked who is going to pay the petrol for driving up and down after Verimark who doesn't care about their customers and also once the mop is assembled the mop is not going to fit in my car's boot so how am I suppose to get the mop home. Walk? I also asked isn't there manuals giving the right instructions on assembling the mop because that is exactly what we did. Then the excuses was I don't know how the assembling of the product works but I must just take it to the shop. This is really pathetic and useless service as we are all happy and nice when people spend money on their products and in the shop but once the problems start arising there is no customer service insight. I will definitely not go back to verimark to buy any other product. Very disgusted in this service. So much for guarantees and all that kind of ****.
