Non existing customer service

In January I returned to parcel of items I do not want. One was broken and the other was not the item it was advertised to be.<br> <br> It took Homechoice 4 months to get to a point where they could confirm that they have received one item. The other one is now a big issue since the post office had a mess up with the tracking nrs and it shows that it is still at the post office. In order for me to get the PostOffice to follow up they need to have the invioce proving the items in the box. I have now requested it from Homechoice 4 times over 2 months. Even gave an alternative email address but still nothing. I have also been told that my installment on those item will be frozen and i don't need to pay but now i receiving threatening sms's if I do not pay!! <br> <br> IS THERE NO ONE THAT CAN HELP !?!?!?!? Last ***. Spoke to Mandy om 18/5<br> <br> Sesto Knife and Eclipse cooler
