Here's an example script to query data from the mygene.info service:

#!/usr/bin/env python                                                                                                                                                                                                                                                                                                         

import sys
from mygene import MyGeneInfo

mg = MyGeneInfo()

ids = [
    "ENSG00000263726",
    "ENSG00000269044",
    "ENSG00000249849",
    "ENSG00000242770",
    "ENSG00000235356"
]

results = mg.querymany(ids, fields=["symbol,refseq"], species="human", verbose=False)

for res in results:
    q = res['query']
    r = 'NA'
    s = 'NA'
    if 'symbol' in res:
        s = res['symbol']
    if 'refseq' in res:
        r = res['refseq']
    sys.stdout.write('{}\t{}\t{}\n'.format(q, r, s))

To run it:

$ python ./query.py 
ENSG00000263726 NA      NA
ENSG00000269044 NA      AC024075.2
ENSG00000249849 NA      AC138819.1
ENSG00000242770 NA      CD200R1L-AS1
ENSG00000235356 NA      AL592466.1

The example list is just made up of a few randomly picked records from GENCODE's current long non-coding RNA gene annotation dataset, but as you can see, not all of them have HGNC symbols, and none in this list contain RefSeq IDs.

Still, this might be useful for your particular list of IDs, or it may give you an idea of how to query records via this tool, generally.
