Since you are new you still don't know that things like this happens sometimes. Especialy in the situation like these days when there is huge number of unconfirmed transactions due to all this issues within community related to fork, miners, bitcoin cash... You've tried to accelerate it but you have to know that thousends of other users are trying the same thing too on the same services so it's normal that you will not make it at the begining. Be patient for a while, keep trying and your transaction will be confirmed at the end.
