NOT BEING TREATED FAIRLY

I purchased a cordless vacuum from Leroy Merlin and this was my first time purchasing anything from this company. I am not happy with this product as it is definitely not quality and value for money therefore I requested a refund. I contacted Leroy Merlin and the service was terrible as I was not contacted and had to escalate my query after 1 week. Their supplier called and informed me that I cannot get a refund. This is not what Leroy Merlin explained to me and this does not adhere to the Customer protection Act! For a big company how is that there is no customer satisfaction. We are purchasing a product from Leroy Merlin and not their suppliers!! I have purchased many items from online stores and tried the product and returned it with no questions asked and with a full refund. I am sure they have many suppliers as well and if the customer is not happy we should be able to receive a refund especially if it is less than a month and under 21 days. I cannot help it if the delay is with Leroy Merlin and they had issues with their online refund process hence I called.
