For this transaction, contact the following user:
vhHe's one of the few users that I've seen successfully accelerate transactions via ViaBTC.
In case you didn't know it, their transaction accelerator (ViaBTC) works but since it has become quite popular, you have to accelerate in the very first second of the hour resets (even if you do, most of the time, you won't be successful):

In regards to these, If both transactions in the chain (parent and parent2) had at least 0.0001BTC/KB in transaction fees, you would have been able to try ViaBTC for these as well but since both are using only 0.00005BTC/KB (5 sat/B), it's not an option.
I've tried accelerating them using Antpool:
https://www.antpool.com/user/prioritiseTransaction.htm?m=savePrioritiseTxThe issue with Antpool is, I had success accelerating transactions with only 1 sat/B, but back then network wasn't as congested as it is today so I wouldn't have any high hopes of those transactions, receiving any confirmation soon (since they still prioritize transactions based on their fees and yours have a very low priority, bottom of their list).
May I know which wallet you used for making these transactions (so I can give other solutions, if there is any)?
