Horrible return service

Bought an item and due it bring too small it needed to be returned, it's been 2 weeks of trying to return the item. The service is horrible, they keep on sending me smses stating they will collect, l stay at home waiting for collecting but get stupid smses about incorrect address given and l wasn't at home whereas been waiting for collection. This is the worst service ever had l known returning an item will be so difficult wouldn't have ordered from runway.
