Stalkbuylove — return failed

Hi

One month back, i made a purchase from stalkbuy love, when i received a parcel i thought of returning one item from it due to the quality issues. I initiated a return requests. At the time of pickup, agent said there is some ean number that they have to enter in there system mentioned on the top or package outside, he entered it but number doesn't matched. He went without taking the product back. I contacted there customer care, they said they will initiate it again and again the same thing happened. I contacted customer care again, this time they gave me the ean number and said to gave that number to the agent at the time of pickup. I did the same but same issue happened again. This cycle continues for four times with the innvolvement of customer care and when fourth time as well return didn't completed, i contacted customer care again and this time they neither reply to my mail nor initiated the return. Append are the screenshots of the coversation i had with them.

Below are the details :
Order number :[protected]
Item for return : red bethany one shoulder top

Please help me with this. Ask them to complete the return requests asap.
