LACK OF SERVICE FROM SPREE!! DISGUSTING!!

SO I requested a return & exchange was done on the 27th November. 10 days ago. I was informed the other day that the entire process takes about 10 days. And guess what... this matter hasn't been sorted within Spree's given timeline and the shoes are STILL sitting with me. I am aware the couriers tried to call me. They tried TWICE! That is hardly trying. I didn't bother to call back because I received a sms from Fedex saying that the collection will take place. I have now just received my FIFTH sms with the pick up reference. And still NOTHING!!!! What is the point of sending endless messages like that and not collecting! I am sick and tired of waiting and hearing one lame excuse after another. The package has been at reception since last week Monday 30 November. I am utterly disgusted with the lack of service from Spree. I will rather shop at Zando going forward. It is ridiculous to wait so long for a return!! I am returning the shoes and want NOTHING more to do with Spree. They think can't be bothered about resolving customer queries.
