Compliance notice received on email

DEAR FRIENDS 

ONE OF MY NEW CLIENT FOR WHOM I FILED ITR FOR AY 15-16 & 16-17. BUT JUST AFTER 2 DAYS RECEIVED COMPLIANCE NOTICE ASKING FOR AY 13-14 & 14-15 RETURN.. NOT ONLY THIS IN "RELATED INFORMATION SUMMARY" TAB, I HAVE FOUND THE FOLLOWING

  FY             INFORMATION CODE                INFORMATION DESCRIPTION  

12-13              TDS 192A                    TDS RETURN- SALARY TO EMPLOYEES(SEC 192A)

12-13              TDS 192B                     TDS RETURN-SALARY TO EMPLOYEES (SEC 192B)

13-14               TDS 192A                    TDS RETURN- SALARY TO EMPLOYEES( SEC 192A)

ACTUALLY THE PROBLEM IS THAT HE WAS NOT AWARE OF TAX SYSTEM AND FILING ITR...NOW I HAVE THE FOLLOWING QUESTIONS.

1--- CAN HE BLAIM ME FOR THIS SITUATION AS THIS HAS HAPPENED AFTER I FILLED THE RETURN FOR 15-16 & 16-17

2-   IF I FILE THE RETURN FOR THE ABOVE YEARS, THEN CAN THE DEMAND OF RUPEES 5000 PER RETURN CAN BE ADJUSTED WITH THE REFUND ( IF ANY ).

3-   THERE IS NO TIME LIMIT MENTIONED IN THE EMAIL UNDER WHICH I HAVE TO REPLY....SO CAN I IGNORE IT             UNTILL THE RETURNS FOR AY 15-16 & 16-17 GET PROCESSED. 

4- IF WE CLICK ON OTHER TAB THEN WE HAVE TO MENTION THE REASONS FOR NON FILING.....THEN WHAT     CAN BE A GOOD REASON TO BE WRITTEN THERE....

4-  WHAT CAN BE THE BEST OPTION TO GET RID OF THIS PROBLEM???

PLEASE HELP ME
