[Scspamcop] General Spam Question

[antioch]

System Info
WINXP SP2 with OE6.  BB Internet connection.

For the last three months I have been trying to get an explanation from my 
IP/ISP regarding the below - all they can suggest is that I change my email 
accounts/addresses.

I am receiving daily, into my Inbox between 50-100 emails marked as SPAM 
i.e.

[SPAM] Purchase medications with..................................

90% of these messages are to other email addresses with my provider.  The 
others are to 2 of my 5 email addresses.

In addition, SPAM is being filtered each day and placed in my MailBox with 
the provider.  They tell me they have no spam filtering service in place?
I do not have any other antispam filtering on my computer - only that 
provided by my IP/ISP, which they tell me does not exist.
I have tried to go to a higher level of tech advice/help but I am constantly 
refused this request.
Each time I try and make a complaint about the problem being unresolved I 
wait over a month for a response.

In the hope this initial post is in the right group, help/advice would be 
most welcome as would direction to the correct group.
I apologise if this thread is too brief, but I think I have given the gist 
of the problem.
