How long did you wait? There are many unconfirmed transactions right now . I'm sure they are getting a lot of messages about it . Please gkve them at least 24 hours .
If you have waited passes 24 hours, Unfortunately, They are the only miners I know . If you're willing to pay viabtc has a paid service which requires a minimum donation of .01, You can contact them on: support@viabtc.com . You can also use their free service tho .
This is also a paid acceleration service although they only accept payment through alipay: https://pushtx.btc.com/#/
btw, Can you post your TXID here so we can help you more .
