How to receive an huge data using WCF Service-How to send hug data. WCF Service Advane

We have created a WCF service and hosted in IIS. It was running fine and we could able to access through http.
This WCF service is consumed by third party (SAP HR), when they are trying to send huge data (50000 kibi) to our WCF service, its failing.
We are able to receive, if the data is 30000 kibi.

Does anyone have idea how to increase the size?
Please find the below details for Configuration settings. Please let us know if we are missing any settings either in config file

ANSWER 1:
 

Note : Provide your comments by clicking below options! Thanks ! :)

Please try  

1.buffer sizes of  all wcf services should be same size  at service side as well as at client side.

ANSWER 2:
Try the following things -

1 - Setting MessageEncoding to MTOM instead of Text
2 - Setting TransferMode to Streamed instead of Buffered
