Am i to send documents every 4 months

on the 25th of Feb i received an sms from let me call it beep bank coz thats exactly what you are becoming - requiring me to submit KYC documents otherwise my account would be frozen in 30 days. As i had just submitted documents last year October and again this year, I called it to ask what documents were required again and why i am always having to submit documents. The call centre agent said a consultant would call me to discuss but upto today am still waiting hence my question is...did you loose the documents i sent? why am i continuously requested to send documents and why has no consultant called in to ascertain what documents are needed and why they are needed.
