Clicks' Safeway products are garbage and they know it - no refund for broken product

My wife bought a Safeway electric blanket at Clicks in Woodbridge, Kempton Park, and after using it EXACTLY as directed for a little over one month it simply stopped working. We took it back and had it exchanged. No Clicks Clubcard was used because my wife doesn't have one. The manager of the store took the receipt from us and swapped the blanket out for another one (exactly the same). After using the newly replaced Safeway blanket for a little over one month it stopped working AGAIN. Upon taking the blanket back a second time, the store refused to replace it a second time. They said we didn't have a receipt but the manager took it from us the last time we went there to replace it the first time. Despite having our credit card details and exact time and date of purchase & replacement, they claim to have no record of it on their system. We have been conned by a charlatan company. It is shocking that Clicks would stock and sell such a **** product that clearly does not work. Is there any kind of quality control or will they sell any old ******* to make a quick buck? Seems like it. I feel ****** and that makes me angry. I used to be a regular Clicks customer but no more. I will never go back into a Clicks store again and will advise others to do the same. I will also be discarding my Clicks clubcard. The service at Clicks is pretty bad anyway and their stock choices are very limited - not to mention their high prices. So it won't be too hard to choose Dischem instead anyway (better service, better prices, better stock etc). I don't suppose we will ever get a refund or a replacement, so that's that. Fool me once, shame on you. Fool me twice, shame on me. I feel ashamed that I let Clicks fool me twice. There will not be a third time.
