Faulty Safeway Electric Water Bottle and Poor Customer Service from Crystal Humphries

We purchased the water bottle on the 1st August 2023, then tried using it on the 3rd but it wouldn't charge to the maximum duration of 20 minutes. This also means that it didn't heat up well enough to deem it useful. We tried all sockets and different powerpoint locations (home/work) but all the same. Tried returning it today using a picture of the receipt which was taken on the day of purchase but Crystal Humphries refused to refund us as we didn't have the paper slip. If Discovery can reimburse a Dischem claim using an image of a receipt then why is Clicks offering such a poor customer experience on a R175 product just to waste our time? She gave a replacement which is even worse - doesn't charge up to 20 minutes like the user guide states. I have purchased a cheapie from China Town previously which was 10x hotter. I promise you that you'd get more heat from a conventional water bottle an hour later than from this safeway electric waterbottle. Don't even waste your money on this product and save yourself the inconvenience and poor customer experience. This is very disappointing Clicks. I have a baby on the way so at least I know not to purchase any further essentials from you because you give your customers a hard time with faulty products which we never used at all. What a loss!
