Bad service

On the 27th March 2025 my niece bought me 3500mb everyday data.I received the notification and it mentioned that I will get 500mb each day,however this was not the case as the 28th March there was no allocation and also the 31st March there was no allocation.I got notifications for each day but not for the 2 days.Today 1st April 2025 I called MTN service desk and I was told that I received the data for the 1st as well but no data no notification received from MTN.This is pure ****ming.Why don't their notifications get sent everyday.They send notifications at 9am whereas they claim to have credited the data at 12:00 am.It very frustrating
