Terrible Customer Care Service.

TB220583 Really terrible customer care service. I bought 5 KG of Bio Classic Washing Powder which is unusable, solid hard. I tried to loosen it with a knife but no luck. I went to the website and reported the issue. I've contacted them several times via email and even phoned. Now they need to fetch the product and first weigh it to see how much I used. REALLY. Also no response from their courier service. Very disappointing service from such a big company :(
