Taarak Mehta Ka Ooltah Chashmah update March 12: Bhide receives an envelope from a mysterious person

In the latest episode of Taarak Mehta Ka Ooltah Chashmah, Bhide finds his home in a mess. He calls Madhavi and she explains how she got a call for an order which led to the mess. The two begin to blame each other until Sonu comes and decides to resolve their problem.
Sonu sits down, and hears Bhide and Madhavi's argument patiently. She eventually favours Bhide over Madhavi.This makes Madhavi upset. Sonu tells her that she loves her baba more than her. She claims Madhavi also loves her baba more.
Madhavi agrees to this and calls her dad a hero. Bhide teases Madhavi and jokes that she is a side hero. However, peace is made and they all begin to dance. Just then, a man joins them and hands Bhide a cover. It's got no name on it. Bhide is surprised. Before he is able to say anything, the man leaves.
Bhide reads that he will receive a surprise gift if he deposits Rs 10,000 in the specified bank account. In the message, it is also written that Bhide should not call the sender of the cover as Rs 200 will be charged from him for 5 seconds. Bhide feels helpless.
Madhavi suggests Bhide should go to Jethalal as it could be his cover. Bhide does so. He goes to Jethalal's house and asks him if it is his cover. Jethalal tells him it isn't. He also points out there is no name on it. Jethalal asks Bhide to go to Mehta's house as he had seen a similar cover once in his house.
Bhide goes to Mehta and tells him everything. Mehta tells him he did receive a similar cover earlier but all of them have his name on it. Mehta sends Bhide to Popat's house, thinking it could be from the marriage bureau.
Bhide then meets Popat in his house. He shows him the cover but Popat tells him this couldn't be his. Bhide doesn't know what to do with the cover. He is seen all baffled.
