So...they acknowledge congested links and clearly suggest a workaround to help mitigate winding up on a congested link.
They did not say that they were seeing congestion from their end of things, only that Bell's shuffling seems to be causing congestion.
When people start complaining and TSI notices that AHSSPIs are congested, TSI usually responds stating that they had a load imbalance problem and are terminating L2TP sessions on over-burdened links to re-distribute the load. Since they are not doing it this time around, I take this as a hint that the current congestion issues are occurring somewhere within the Bell cloud so TSI cannot determine which links are misbehaving with their current tools.
