Correct, they extended my mom's line by 30 days.
I checked
https://www.alfa.com.lb/en/account and *11# on my phone. The expiration date is still the same (2nd of June).
No 30 days were added. I have the regular prepaid card which I renew with the 39,000LL alfa scratch card.
It is fine though. If there are no open stores in Lebanon in the next week, I have bigger issues than recharging my phone :)
