Bad service - this is why people are scared to purchase online

The sizing on the advert does not mention that the casing is a different size to other products, when I contacted the call center to tell them, they said “you ordered and it was delivered and we won’t take it back.” Bad service. I want to remind you that on all the other buying sites. If goods are incorrectly ordered because of such happenings, and even if you have ordered the incorrect goods. They will take it back. On your terms and conditions there is no mention, where you mention “ You can’t return if” :- that is you have ordered the incorrect goods you can’t return it. Sites like yours is why people are nervous to buy online. Ridiculous. I am now stuck with speakers that I can’t use as they are the wrong size!!
