Monster Avis 2

I have a Monster sound system. It is not working properly. I have emailed them twice (once a week ago and once only an hour ago) and no reply. But I think that my problem needs a telephone call.
The numbers on their website do not work , leaving a message saying phone contact is not possible.
The online service request form is biased at the US and I am not at all sure that my requests have gone through as the form requires a US state and will not accept my European number.

The service is abysmal.

The sound quality is great, but this counts for naught when the headphones break again and again and again.
There seem to be some serious problems with the build quality and the customer service was amongst the worst I'd ever received.
You can find other companies that also have awesome sound quality, but also good build quality and customer service.
I will not buy another monster product after my repeated failing headphones.
