Return request unfifulled for over a week

On the 28th April I requested an item to be returned to spree the item was not fitting correctly , since the request the item was not picked up this is unacceptable for the simple fact that my experience with spree when refunding goods they are extremely slow and poor in service in either crediting the customers account or paying cash back . Because I have not had my item picked up for a week now I will not accept waiting another week for spree to forward my credit I have an item I would like to purchase and I'm not prepared to wait for my credit and stock runs out on the item irrespective of that I want my credit it is owed to me I have waited a week already , spree pick up,the goods and process my credit with urgency I refuse to wait for my refund I want to spend it now it's my birthday on Thursday I'd like to purchase immediately
