Unhappy Game customer

Game should improve their customer service. Usually my experience with game hasn't been so bad. My husband and I went to buy a vacuum cleaner, we knew what we wanted and yet once we were there were spoken out of it by not 1 but 6 game attendents... Their selling points to buy the Bennet Reed titan instead of the hoover was that it had power, it was easy to clean and that it wouldn't blow all the dust all over like the hoover would. Oncemy husband and I tried it at home we found that it was not as powerful as promised. When we used the "self clean" option it made more mess taking out the filter to empty... And the blower side blew dust all over if the vacuum was facing the wrong way. We were unable to take the vacuum back within the 7 days (due to certain circumstances) but we took it back 13days later and it was booked in for assessment. 13 days later after no phone call to reassess why we were unhappy we were told to collect as "nothing is wrong with it" yes nothing may be wrong with it but number 1 we did not get what was promised and number 2 I'm pretty sure nobody wants to make more mess trying to clean their vacuum cleaner than the mess you clean... Game should either extend their return time or be more customer friendly in understanding the complaints of customers. Not a happy customer today.
