Game Store Clearwater, service has gone to the dog's in these trying times

Game stores is such a big chain store and such a big brand name but ****ty employees working for this store and dragging their name to the drain. I am a Makro loyal customer, however last year I decided to give Game Clearwater a chance by buying a complete defy stove from them which they did a great job and beat the price for me as makro had already closed on this day. The quality of the receipt I got faded within two days, I therefore did not get a chance to make a copy of the slip as proof of purchase. However, a year later I have a problem with the stove, I went back to the store and was attended by a lady in the name of Lynette, after giving her all my details she promised that she had escalated my query to Gugu to retrieve the receipt for me. I must say this took a week with no word from Gugu. I then decided to contact the store, after a very long time of me being sent from pillar to post by the receptionist, I eventually got hold of Gugu. The most arrogant, defensive and rudest individual I've ever came across. This lady fits perfectly in the government offices to go give a ****ty service there, not a good image for your establishment. She told me, she was away for a week and had not seen my mail that she never attended to, she also informed me I was not allowed to instruct her on how to do her job. In 5he end of all this argument, Gugu had not heard a single thing from my query. She only dwelled on being defensive. I've lost hope on Game stores. I regret not buying this stove at Makro, Makro is very advanced, by the time you walk out of the store, your invoice is on email. Now I have to go back and forth just to get my slip retrieved, how much more when I then have to get my stove attended to? Please take back your ****ty product if you cannot help me.
