My only experience is of the returns process since the hole punched through the shipping and product cartons required such force that I was concerned for aesthics and functionality of the product.
Of course the the burden of proof then fell on me while the courier is allowed to go about their drops. Then I have to pay interest on my credit card while I wait on someone to evaluate my return request. The whole experience, including the collection by a different courier, wasn’t one I wanted. I only wanted to be a customer but got inconvenience and no product for my effort.
