Is tackleuk.co.uk Safe?

A very bad customer service. Following a delivery error on their part, I am forced to return the wrong item at my expense. They preferred to promise me a discount on my next order .... ! In the following command, I had to beg my discount, they would not give it to me. A shame how these people work. It is the customer pay for their mistake! I was treated like crap even though I was a good customer. delivery not respected
