Please who can guide me to any bitcoin wallet service that does not charge for miner's/transaction/network fee for sending bitcoins??? i really need it it ASAP
There is no such thing. The required fees for inclusion are not determined on a per-wallet basis. You should do some research to learn why fees are needed, and how to calculate the recommended fee-rate. Some wallets allow you to fully customize your fee (e.g. Bitcoin Core) and even send with zero fees. However, a transaction with zero fees is likely to never confirm.
