HDFC Bank's Online Mobile Recharging Facility Not Working

I usually recharge my pre paid mobile SIM card, with the help of HDFC bank's online mobile recharging facility. This facility saved a lot of time and was very much convenient to me as I didn't have to walk up to the nearby mobile recharging shop to recharge my Airtel pre paid card. I used this facility to recharge the SIM cards of other members in my family.

But for the last one week, I have noticed that the mobile recharge option by HDFC bank is not available and whenever I try to access this service I get an error message stating "Due to some technical issue, Mobile Recharge transactions have been temporarily stopped until further notice". This has been a matter of serious worry for me as I cannot recharge it sitting in front of my system. But I hope that this facility would be back soon and HDFC Bank will make sure of fixing this issue. I have not seen this issue with HDFC Bank's website so far, so this may be a temporary technical problem.
