Vodacom - Daylight ******s

About 3 weeks ago i received my new statement for the amount that will be deducted for July. Immediately i knew the amount was higher than last month. I upgraded in January of this year and paid the new upgraded amount end February. This to me means it is now a fixed amount and because i have a new device and new package the insurance etc had to be deducted also end of Feb. But now they come and up my insurance by almost R100 not only this they charge me twice on it in July. 4 Months after i upgraded. I called the call centre 4 times with all of them telling me they will call me back and it will be sorted out. I have to this day hear any feedback. This is poor to say the least. Everybody is struggling with this Covid **** now vodacom comes and *****s money as they feel like it
