The service is not clear & not honest!

In the website states that if I order before 12 I will get a next day delivery.

I made the business cards order and used a discount code sent to my email, then I found out that there is no next day delivery! When I asked the customer service about that they said "I can see you have used a voucher code, next day delivery can not be selected if you have used a voucher" !!!!

No any information on the website mention that if I use the discount code will cancel my next day delivery!! purely because i came with a discount code sent to my email!! which made me now regret using the code as i am very in need to these business cards before Thursday! They wasted my time as 12pm past and now it's very hard to find a place offering next day delivery after 12pm!

I'm very disappointed and this experience made me fee that their service is not clear and not honest!

I will never use them again.
