Query: Three months of use and poor/no customer service

I received this for my birthday in Nov 07. You need the large filter to get enough espresso for my size lattes. It clogged on 2/11/08. I cleaned and cleaned it per the directions wasting a lot of ground beans trying to get the filter to work. I was told I would be sent a new large filter. Still waiting. Called back 2 weeks ago and still nothing. Requested to return my machine and I got nothing from customer service.DeLonghi EC155 Espresso Maker
