Thank you @sur-riti for bringing your problem into our notice. I can understand your problem is serious one so we tried the wallet you mentioned.

You will be surprised to note that this problem is already resolved. I tried and was able to bring 148+ Steem to Steemit's wallet.

I am sure you can also be able to do the same. Oh yes, I had tweeted to the wallet's account a few days ago
