Unbelievably bad service. After plcing an order, I have been asked for a proof of delivery address - a copy of a lease, utility bill, etc. After providing such, which is unprecedented, I have been asked for a proof of a billing address! Never ever any supplier has asked me for "extra paperwork". Got frustrated and decided to cancel the order, however a refund has not been offered: I was told that I have to claim it through my bank, since they have not received any payment, even though the payment was clerly credited off my bank account. I have not come across such supplier, will never use them again. It is like a spam company.
