The matter of being aggressive with DLJ also applies to TDWaterhouse. I had to send formal letters to division VPs to force them to give me my 30k points. I also had to do the same with AMEX when they had an email promotion involving a money market account and 10k points.
The usual excuse is that the process of crediting points is a manual process and there are too many people signing up for the promotions and too few people to handle the workload.
