have since corporations

Don't get what does " have since corporations" mean.

Context:

S: Good afternoon. I'm Smith, John Smith of the British Overseas Trading Co., London. I came to the Fair two weeks ago and have since corporations. I want to make use of my present visit to settle our claim on you for the 100 tons of Bleached Cotton Waste, as per Sales Confirmation No. 1250E.

==============================
s/s = same size?

S: I hope so. We're very sorry to have cause to complain about the quality of the cotton waste you shipped to us by s/s"Mette Skou". We have written you save letters on this subject. No doubt you have received from our London office the outturn samples of the inferior quality cotton waste as well as well as our letters giving full details of this claim.


PS. Do you know what is Mette Skou?
