Bad Service

I sent back a set of Sennheiser headphones on 22 May according to your email they were sent to Sennheiser Electronics SA on 30 May. It is now the 5 June, so I reached out to them to find out what the story is only to be told that they have not received them, the service department has asked me to ask you for the proof of delivery so they can see who signed for them.

This is disgraceful I have asked so many times that this is urgent these are not for pleasure they are used for work I need a new pair asap.
