dolce gusto

I went to Checkers Hyper 2 weeks ago to replace a faulty Dolce Gusto bought at the Black Friday sale. I didn't have my receipt with me, so I returned the following Sunday to the same Checkers Hyper @ Forest Hill. I waited 30mins or more while \stock was checked"and was told nothing could be found and I would be contacted the following day by Natalie who gave my brother attitude. How could there be no stock of such a prominent brand and popular product?! I was contacted by Natalie the following day (Monday) only to be told that they were still sourcing the product. I heard nothing after that and decided to return to Checkers. Natalie was off duty and I spoke to the store manager who said I would be contacted the next day. I was contacted last night (30 June) only to be told that there was no stock and I would be offered a display unit. How could there be no stock in the area or even province??? What will I be offered in exchange if the display unit fails on me within its warranty period?? Deeply disappointed by Checkers Hyper"
