Spouse Visa(FLR) extension, put me to 10 years route

Hello can someone please help me and guide me what can i do?? i was on 5 years route visa . my 2.5 years expired on 12th of nov but because of the delay from bank i submitted my visa application on 14th of nov. actually i requested bank for change of my address and my husband's bank statements. they took 2 weeks and 3 days for this all bcoz of some problem in their system. and just bcoz of 1 day delay they changed my visa from 5 years to 10 years. however bank sent me letter explaining their fault. is there any way to change it?? i dnt even have right to appeal.
