Little play land does not want to refund me

I have lodged a dispute with regards to the online purchase from little play land. I have purchased the parcel at the end of November 2020, however I did not get my parcels yet. I have sent them an email requesting them to cancel the order, however what they did is they processed the order again. I sent them numerous emails requesting my refund I think until you intervened then the parcels were posted to the Mayville post office. I will not fetch them because I specifically told them that since the turn around time to deliver a parcel to a customer has expired I have no use for the parcel anymore. The receipt that you get from the post office has been sent to me but I am not gong to fetch them until return to sender, I want nothing to do with them but my refund, to top it all I have made contacts with 2 different post offices to confirm that the parcels but then has not reached the destination. I even went as far as asking for the an email from the post office to confirm that I have not received my parcels. They have such a bad service, you end up talking to different people telling you different stories, they don’t even put the customer first. I will not fetch those parcels until returned to sender. I just want my money back, how can I wait for 3 full months to get my parcel, which process are they following? Little play land is the most *********** online company I have ever met. I need my refund back no stories, they must phone the post office to find out if the 2 parcels are still there and pay me back, because I specifically asked them for my refund before they processed the order the second time. There is no way that a customer when is requesting their refund due to bad service and should not be given, I really need your help on this one.
