Wolverhampton businessman feared kidnapped: Deafening silence makes family fear the worst
The children have no idea whether their father is in trouble and needs their help.
The silence from Ranjit Singh Power is deafening given his track record of calling home two or even three times every day.
All the Wolverhampton hotel owner's family can do is wait and plead for anyone who knows anything to come forward.
Their minds will race with the terrifying prospects as all they can do is speculate.
They fear Mr Singh Power, owner of the Ramada Park Hall Hotel, may have been kidnapped or even killed while on a business trip to India.
His daughter Emma, aged 26, knows her father to be a 'very strong man' who was 'constantly on the telephone' while he was away until everything went sickeningly quiet.
She and brother Gian are desperate for news about him after he flew out of Birmingham Airport on May 7 and was believed to have landed at Amritsar Airport in the Punjab. No one has heard from him since.
The charity the Lucie Blackman Trust, which includes the Missing Abroad appeal, says a British national is reported missing in India as often as every two to three weeks.
But chief executive Matt Searle said: "In many of those cases, happily, the person is found quickly because it turns out they have been in an area with poor phone signals or internet access.
"They think they were sending messages home but it's been like operating their phone in flight safe mode, the messages just haven't got through and they did not realise.
"Kidnap in India is, thankfully, rare."
It does happen though.
In 2013 British nationals Kanapathipillai and Salajah Thavarajan were abducted by a group posing as tour operators after arriving at Chennai (Madras) airport.
The Londoners were found four days later in a village more than 100 miles away.
The couple's daughter received a ransom demand of £300,000 by phone and passed on the information to police, who contacted their counterparts in India and rescued the couple while they were being transported by car.
And in January this year, five men were arrested for kidnapping a young Japanese woman, who managed to escape after three weeks of repeated gang-rape at gunpoint near a Buddhist holy site in Bodh Gaya.
But Mr Searle said India was better than many other countries for helping the British authorities to track people down.
"It's not brilliant, but it's certainly not the worst," he said.
"Contacting Thailand you get the impression the last thing they want to be bothered by is finding a missing foreign national.
"It is not as easy to find someone in India as it is in America because of the communications network."
The Power family are already in touch with the Foreign and Commonwealth Office which has reported Mr Singh Power missing in India.
Mr Searle said: "They will now be working with the embassies and authorities in India.
"They will know to look out for his name on any official reports from hospitals or even prisons and arrest records.
"In terms of the British police, they have no jurisdiction in India.
"All that can be done locally is for a report to be filed with Interpol."
The Lucie Blackman Trust is currently working to try to find out what has happened to 3,500 people missing abroad.
"There is never a pattern to this," Mr Searle says. "Sometimes we have cases that throw up a whole new reason for someone having gone missing. It can be medical, for example someone suffering from dementia or another mental health issue. In some cases people do not want to be found."
