No customer service from Aspen

I phoned aspen to complain about the formula S26 to first be told it's the security and the receptionist is on lunch so I must phone back later. Another call later and I was promised that Margaret will phone me back. Third phone call later I got disconnected and last call I couldn't even get thru. I have a 4 month old baby that refuses to drink any other formula and the S26 I bought smells of fish so she refuses to drink anything. This is ridiculous since I have the formula to proof to them that something is off with it but getting thru to nobody.. help...
