Salesperson **** - product does not work

I was buying a vacuum cleaner in Game Bel-Airs Mall, and electrolux floor cleaner, but then your verimark salesperson said i must rather go with the MINIMAX Upright 4 in one, as it was better and on special, so i took it as she said i can vacuum a 2 bedroom flat daily. well she **** and the product over heats and cuts off constantly. I have to wait for an hour for it to cool down to continue vacuuming. It is good for small accidents and perhaps a car but not full on floor cleaning, this was 2 months ago and now i regret buying this useless MINIMAX, ironically the thing that supposed to pick up dust will now collect dust in the cupboard. I want a better product for day to day floor cleaning please OR a full refund and i will not pay a cent more than what I paid for the MINIMAX price. I am also thinking twice of buying a verimark product again, this was my first and last experience with verimark
