dozen ways to skin the cat

having the  email sent directly to the webservice/tech support
provider will not reduce/change their 48hr response time
and depending on how you did it, you might not get a copy
of it either ..

best way to do this ... on your side ...
	vi /etc/mail/aliases

	#
	# keep a copy for yourself ... and end a copy to them
	#
	care:		localcopy,customer1 at webservice.com

-- on their side
	vi /etc/mail/aliases
	#
	# they receive incoming tech support email requests
	# and send off a reply .. noting the original email info
	#
	customer1:	themself,replied at company1.com


they reply to customer1 and you also get a cc of their reply
at replied at company1.com  that its been processed

and hopefully, your contract calls for payment for 
correct and timely answers sent to "replied at company1.com" 

imho, tech support and other support services should be internal vs
outsourced
