Edgars online purchase

Just had a baby then I ordered my baby's clothes online. The day I was supposed to get the items,I get a message at around 07:23am from their chosen courier that the parcel would be sent and got a delivery pin. At around 12: 40pm I receive a message again that my parcel was delivered successfully. Contacted the courier concerning the issue and was told that the parcel was sent back to the sender per the sender's request and that they would investigate and get back to me. They contacted me a day or 2 later to confirm that it was indeed send back to parcel ninja on their request. I contacted Edgars and the lady seemed to have no idea of what's happening,told me she would investigate and get back to me which she never did. Had to call again few days later and send emails and was told they would reverse my money within 7-10 days without a real reason why they requested the parcel to be sent back to them. I asked for the reason and they told me that they would contact the courier and get back to me and they never did. Called again the following week,trying to get a feedback on the incident and was told about the refund again,that they would reverse my money, of which I never got the official message that it would be reversed and whatsoever. The lady asked if I got the message for the reversal,told her no and she told me that she can see on her side that it isn't processed yet and that she would investigate and get back to me. Told her I wasn't calling for the refund, I wanted to follow up on the courier incident. She told me she cannot give me any feedback,they will need to investigate and get back to me. I'm kind of disappointed as this has caused a real inconvenience on our side.
