Skype email

Everyone remembers the forced transfer from MTS to the "European" tariff?

But today I received a letter from Skype:

"... funds in your account will be deactivated after 30 days (days)
According to our data, you have not used the funds on your Skype account for quite some time. Money in your account is deactivated if you never use it for 180 days. .. "
')
If I do not want to use the paid services from Skype now, why can I lose my money? (if I correctly understood the meaning of the word "deactivate")
