Shocking service - quick but totally wrong and refund not coming

They are useless! I will give them that: they come quickly. But expect NO relation between what you order and what you get and then there is no receipt, nothing that explains what is missing and why; irrelevant replacements and no phone number one can call. I'll never use them again. Still awaiting a refund! And when sending an email they do respond automatically but they give a number that doesn't work.
