Disgusting service from Verimark

I purchased an upright vacuum cleaner from Makro just over a year ago, this is the 2nd vacuum cleaner like this of which the 1st one was also faulty still within warranty, every time my vacuum cleaner went in for repair to Makro I was without a vacuum cleaner for roughly 2 months so now recently I decided to contact Verimark directly hoping I would get better service but sadly the service I have had from them so far has been even worse or should I say non existent...both vacuum cleaners I have had other than the other problems it had that was repaired have another problem... the silver flap at the bottom front covering the motor/exhaust blows off when you use the vacuum cleaner and then the dirt blows all over the house, I went to Verimark in Tygervalley and there the sales lady was unable to help at all saying she would get back to me, a few days later she called me and stated that although she is unable to help I should still bring the vacuum cleaner in so she can see that it blows off (a waste of my time if nothing is going to be done about it) I then went to Verimark in Canal Walk and the sales lady there informed me that a new flap should be purchased and the big white filter should be replaced....even though I knew this was going to make no difference I humoured her by purchasing both and went home and put new filter in and replaced flap, next morning when I wanted to vacuum it was barley on for 2 minutes when the flap blew off and the dirt was blowing everywhere!!!! I went back to Verimark Canal Walk and dealt with Alta who admitted that Verimark is aware of this problem with this particular model but seems to be doing nothing about it, she called Patricia (customer service manager at Verimark) while I was in the shop and this is the brilliant advice given to Alta to give to me "please inform the customer that we will not swap out the vacuum cleaner and the customer should just FIDDLE with the flap" Well Patricia.....my question to you is....HOW THE HELL DID YOU MANAGE TO GET YOUR JOB GIVING THAT KIND OF CUSTOMER SERVICE???????? Please note, I did not ask for a new machine as I know the new one will do the same, I just want a working vacuum cleaner so I can vacuum my house without the dirt flying all over...please also note that my Vacuum cleaner is still under warranty!!!! I still went home and followed her pathetic advice and lone behold the flap is still flying off the vacuum cleaner...thanks Patricia for your genius advice!!! last week Tuesday I tried calling Patricia and of course I could not get hold of her, so I left a message for her....1 week later I am still awaiting her to call me back, I also tried calling Patricias manager (unfortunately I did not make note of his name) but he was also not available and has also not bothered to call me back - my mother purchased the same vacuum cleaner and her silver flap is also blowing off - maybe if I complain here I might get some service.....If not then I will post this along with pics of the vacuum cleaner all over Faceboo****!!!!!! Eagerly awaiting a response. Mandy ********** 304
