I doubt the rules apply to clis.
Too many accounts is better than you have enough and we're not budging.
Just leave them alone and try it once per month until it works again. Aim for Nov 1st or something easy to remember and try it on the 1st of the month until it works. Then go back to the 90 day cycle.
they give out cli's like crazy for this card, in some cases people that started at a 1k limit hit 55k by the end of their first year. this is one reason that i like it.
Don't get discouraged. The sweet spot is 50% of your income w/ BOA unless you have extensive deposit accounts. That should grow to 30K over time.
