Why doesn't Bitcoin-core Wallet app transmit payment?

Bitcoin-core Wallet app no delivery transaction

From the 18th of March to the date Bitcoin-core Wallet app retains my satoshis with the
message "this payment has not yet been transmitted"; they invite you to make payment
increases in the network fee in the order of 0.000288 satoshis, increments that
I have paid 2 on the 18th and 2 plus on the 19th for a total payment increase to the
network fee of 0.001152 satoshis, more than generous amount to call the attention of
the miners (these increments do not record any address). The address generated by
Bitcoin-core Wallet app after receiving, and consulted in explorers as blockchain records
that "There are no transactions for this address". As additional data Bitcoin-core Wallet app
received satoshis from paper wallet. As you can see it has taken more than prudential time
to get any results. I don't know what may be happening in the menpool, I don't know who may
be responsible for this delay, I don't know who to complain to, I only have the community
interested in Bitcoin continuing to be decentralized.  For this reason if someone can
respond by clarifying what is happening with this deficient delay will be very welcome.
In short, use Bitcoin-core wallet app to receive a paper wallet, receipt accepted and
generating new address, invite to increase the action network commission that is made several
times, to date impossible to use the satoshis. Again community interested and knowledgeable
to respond, thank you very much.
