Airtel — networking and my current plan

Address: 787055

Dear sir,
I am a post paid customer bearing no [protected]. That there is frequent network issue in our locality. I have complaint many times regarding the same but it seems you are not taking the matter seriously.
Secondly i am using my plan 549, with billing amount of nearly 770 per month and it seems it is of no use as the prepaid customer is getting all the benefits recharging 399.
I request you kindly fetch me with the best plan or guiding me to surrender this post paid connection at the earliset.
