Wrong Number Ishita

Did anybody notice in yesterday's episode(15th Oct) where Mihika and Ishita discuss abt S Bhalla report over the phone, Mihika gave a mobile number to Ishita which she found on Ashok's office table. The number Mihika gave starts with 99290*****,whereas Ishita dialled number 9810******. and fun part is tht wrong number belongs to Sarika...
