Ridiculous service

I ordered an item online, cause that was the only method to order the item. While placing the order the website advised 2- 5 days for delivery which was reasonable as I was purchasing a birthday gift. Then I received an email thank u for ur order with 2-5 days. But awaiting payment yet I made an instant payment I freaked an called the call centre an was told don't worry the order was being processed an I should get my order in the week according to the 2- 5 days. Today I call an advise so it's 2 days an I was advised by the manager please go read the terms an conditions as it's working days an not days... An the supplier has his own days. This made me furious because the website is misleading. I asked please call the supplier or find out what store can I collect the item from. I was told how it's my fault for ordering the item an I must read the terms an conditions. If I want a refund I must wait 7 days. Take alot is impressive here I feel like as a client I did something wrong yet nothing was made to make it right. Not a call to the supplier to help with the delivery... Ridiculous service
