Horror of G-star Jeans online store

I bought 2x G-star trousers eans online did everything, I waited about 4 weeks for my order. Once it came to my surprise one of jean was big size, so I returned as per their return policy of all communication was fine & received it. Eversince I waiting for my refund called & email they calls don't get through but on emails they claimed that they did refund me with no proof as they don't have my account number to transfer my funds to me.

So this G-star jeans online doesn't care I wish can learn this experience shop only on those SA stores or online with SA only as they are locally located that Netherlands based G-star jeans online it's very bad with very poor customers service & arrogant people.
