No response from Spree

I have been trying to contact spree since the 29 July when I send my returns request!! They still have not collected the parcel. I have sent two separate emails pertaining to two separate purchases-no response! When I call the call centre I hold for ten minutes before putting down because it's costing me money to wait on the line each and every time I call. I know with the sale Spree was inundated but come on, such poor service!
