ONLINE PURCHASE DISASTER

On the 26th of April 2015 I placed on an order via Edgars Redsqare online store, it is now the 30th of April and the status of my order is processing I decided to contact the call centre where I was placed on hold before even giving information with regards to my order therefore I wonder what the agent did for the first 5 minutes while I was on hold. I thereafter gave the agent my contact details and was placed on hold for another 15 minutes of dead air. I was advised by the agent that the product is still being sourced and therefore I will have to wait until May the 5th. I cannot fathom how an order placed on the 26th of April 2015 will now only be delivered on the 5th of May???? had I known that the item was not available I would've simply ordered something else or walked in store this is a complete inconvenience as this is a gift and now it will be delivered days later than I calculated as per the delivery information.
