Online store disappointment

I ordered a product online.

The incorrect product arrived (I ordered a photo frame, instead 3D printing filaments arrived). It was completely the wrong order.

This morning Incredible Connection advised I must go into a store to rectify the issue. This is completely unacceptable - the error was on their side and they should be rectifying it by collecting the incorrect product and delivering what I ordered and paid for. The reason I purchased online is because I am unable to go into a store at the moment.
