Transactions stuck at pending on ropsten test net from one day

I am Writing a simple script for ERC20 token transfer method. which sign transaction offline and then submit it to network.

Transfer method encoded data :

var encoded = await MyContract.methods
              .transfer(receiver_address, 10);
            

To get nonce of sender account :

var nonce = await web3.eth.getTransactionCount(
              sender_address,
              "pending"
            );

To get estimateed Gas of latest block:

let estimatedGas = await web3.eth.estimateGas({
            "from"      : sender_address,       
            "nonce"     : nonce, 
            "to"        : address_contract,     
            "data"      : encoded.encodeABI(),
        });

Here i create a tx object using ethereumjs-tx cdn link:

let privateKey = new ethereumjs.Buffer.Buffer(key, 'hex')
            var tx = {
              nonce: nonce,
              gasPrice: web3.utils.toHex(gasPrice),
              gasLimit: web3.utils.toHex( estimatedGas + 1000000),
              to: address_contract,
              data: encoded.encodeABI(),
            };
            let tx_object = new ethereumjs.Tx(tx , { chain: 'ropsten' })
            tx_object.sign(privateKey)
            let serializedTx = tx_object.serialize();

Then i submit transaction to ropsten test net:

     web3.eth.sendSignedTransaction('0X'+serializedTx.toString('hex'))
              .on("transactionHash", function (hash) {
                document.getElementById("error").innerHTML =
                  "Transaction Hash :" + hash;
              });

Gas Limit of transaction is :

Gas Limit:1051110 also tried with gas Limit of latest block 8000029

Gas Price of transaction is :

Gas Price:0.000000002 Ether (2 Gwei)

But my problem here is that transactions get stuck at pending state from two days.
i am attaching image and link to contract address

enter image description here

link of contract: https://ropsten.etherscan.io/address/0xdc11d98aa50b99a948a4fc2e159c30c5ba9a8364

following are version of web3 and etherumjs-tx:

  • web3 version 1.0.0-beta.34 (also tried 1.0.0-beta.26 and @latest)
  • Ethereumjs-tx version ethereumjs-tx-1.3.3

I don’t think that there is problem with my gas Price or gas Limit.
