Dissatisfaction in return not happening!!

This is my first time returning something I bought and what a disappointment I took it back to the delivery point 10min after I collected it have just opened the delivery package box not even the product as I could see it was not what I was look for and won’t fit so did not even try or open it. This is now days later and no refunds or communication I am guessing the playing a power game as they already have the money so they have the upper hand . I have been buying from them for long now but will probably go back to the old method of going to the shops and get what I need. Disappointed
