Bad service received from Vodacom Southern Centre Bloemfontein

Good day. I went to upgrade in March of 2022. When i upgraded i requested the consultant to keep my package as is this must include my 500mb data each month. In April i saw that it was not included and i phoned the consultant. She then advised that she will request Vodacom to add it to my contract. In may it was also not included and i phoned again and the consultant advised that there is a promotion on the 1gig data and this will cost me +- R40 extra a month and i asked her if this data will show on the same day on my acxount which she rep**** to as yes. A few days later i phoned again and asked why the data does not show yet and she said it will only show on the 1st of June. Well today is the 1st of June and yet again i have no data. Untlil now i had to use my own money (which i vurrently dont have because i am on maternity leave). Please assist urgently! And i would like a refund on the data that i had to pay for!
