Moip API v2 incorrectly handles international phone numbers on a «POST v2/customers» request

I use the following API request: https://dev.moip.com.br/reference#criar-um-cliente
I pass an international customer’s phone number:

{
	<...>
	"phone": {
		"countryCode": "7",
		"areaCode": "962",
		"number": "9197300"
	}
}

Moip incorrectly returns this number in the response:

{
	<...>
	"phone": {
		"countryCode": "55",
		"areaCode": "96",
		"number": "29197300"
	},
	<...>
}

I have got an answer from Moip:

Today we do not support creating clients that are from other countries that are not from Brazil, so this error occurs.
We do not have a forecast to be international.
