Bad service and repairs

I bought my second Russell Hobbs mistfan from take alot since the first one fan blade just decided one day after a few months of using it to disintegrate into pieces. Takealot refunded me and they had the mistfan on special again so i bought another Russell Hobbs mist fan from them. Well after just over a year the fan just decided to stop working. I send it back to Takealot and they told me they will send it to there supplier or repair centre to assess thr problem and will come back to me, they told it will cost just over R400 to fit a new motor as the motor packed up. This is not covered by the guarantee as you need to register on the website for the two year guarantee . I had it fix and it came back with another problem where theres a short inside the fan becuase you can hear the wires shorting inside and the lights going on and of and then I just heard a bang and the fan went dead. Now I know whats going to happen I'm going to contact Takealot and they will collect and the tell me I will have to pay for the repair again, now why would I need to pay for this because they did an assessment on the fan so if that was also an issue they must have picked it up and told me that the wires was also not connected correctly. But this happen due they do not doing a quality check on there products and the company they use for repairs is not competent to do the right job, unless this is some money making **** where they fix the one problem and broke the other so that you must send it back again and pay for repairs. At this stage the fan came back with more issues then when I have send it for repair.
