Transaction Problem Newbie

[mickmoll]

Hi All,  I have a problem and searched the web for 2 weeks and cannot find a solution.
 I have a putincoin wallet on my mobile which seems to be very basic. I have only used it twice and both sent transactions ($300 each+) are unconfirmed after 2 weeks.
Both transfers going to same address which is also mine where I can see them , but both waiting confirmations.
 There is no way to adjust the transaction fee in this wallet  and seems to be fixed at 26.81sat/b per byte which seems way below the current transaction fees.
 Have you any idea how I can sort this out?.

Thanks in Advance
 Mick
