Had my original B changed to L for 5 days and now back on 5 year B as independent.

Paid 300 CHF for L Permits for whole family just to come back 5 days later and pay 130 to change them to B..
While I wrote the migration in February that I am in the process of making a business plan to hand in end March.
(1 month before my work contract expires April 28th and 1 year before my original 5 year B Permit expires)
They still decided to change my B permit to L until April 28th.
Got the L Permit March 27th handed in my business plan March 28th and got my Independent B Permit April 5th....
