State Bank Of India [SBI] — SBI net banking--multiple malfunctions

Address:

SBI, Mumbai

I have been using SBI net banking for years. Since last many days creating new fixed deposits of any kind( STDR & RD) has become totally non- functional. My wife and I have been trying many times daily on our respective user IDs. No explanation from SBI is forthcoming. In my wife's net banking there are other mal-functions too, like she can not even close existing deposits. On tweeter, they asked for details which were sent. But thereafter, SBI is keeping mum. I cross checked in Yono. Surprisingly, there too, other functions can be done except opening new fixed deposits !! Does SBI not want customers to invest in Fixed Deposits online any more??
