Ongoing Data issues (Data bundles not loading)

I purchased data in advance with Vodacom (R899 for 1gb data pm for 12 months and a separate 500mb data bundle pm for 6 months). This was great for many months until last month where I got my notifications saying my 500mb and 1gb were loaded however when I immediately checked my account not data was loaded. Last month I called in and the person could see nothing was allocated and then escalated to the technical team.

Once it reached the technical team they just closed the call and said I had used the data. I continued to call and complain, once of the consultants said they would load 1gb out of good faith and so I just cut my losses until again it happened this month. The same thing happened, call centre can see that the data was not allocated but everytime it goes to a technicial they just close the call and this time everything is apparently all in order but still no data bundle loaded. I even had once technician send a message saying he check and I had not purchased a data bundle and that I should check if money came off my account!!!!! Clearly didnt bother to read the issue I am having!!! I am so tired of this because I have literally called in over 10 times and every time nothing happens.

Most of the time the call center is amazing however the people who can fix my issue is the technicians who never do their job! At one point it has been over a week that had gone by without a resolution, the call center agent just told me "Sir please be patient, a technical will call you tomorrow by 4pm the latest, I promise you" after I told him I do not believe someone will call me. Guess what? Two weeks later and nothing!!! What is scary is the fact that I am being forced to move to another provider because if I purchase data bundles in advance and they clearly not loading onto my account then how can I stay with Vodacom? and on top of that it just shows that when I do have an issue I cannot rely on Vodacom to resolve my issue. I am begging Vodacom, please can you get someone who is competent to resolve my issue urgently so that I am not forced to move to another provide
