Olympia Embossed Pullover Hoodie Beige

I ordered the wrong sizes and immediately after I received the package I contacted customer service to let them know that I wanted to exchange the items for a bigger size. Thye mention in the website to email them so they can give you a number for the return/exchange. I must have emailed them 15 times and I am still waiting to hear from them. Since I didn’t want the exchange period to expire, I decided to ship the package back to them (I paid $17 for shipping) and I emailed them to let them know in advance. I also provided them with the tracking#.
It has been over a week since I shipped the package, they have already received it and I STILL have not heard back from anyone yet. Now I have spent over $150 que I have nothing

Please email me back!!
