Completely disappointed and tired of struggling!

I am tired of struggling like this. I am a loyal Vodacom customer, but for some reason I have to struggle with everything. First, my contract was supposed to expire a few months ago but the "system" said it expires February 2021, then eventually I got them to change it to the end of November 2020 (which was actually still not the correct date). Then I phone in again at the end of October to make sure my contract gets cancelled end of November, but I agree to take a month to month contract with R125 airtime and 5gb data. Today I got R125 airtime but NO DATA. So I phone vodacom and speak to a lady who's line keeps dropping because she is apparently working from home due to covid. Eventually I give up with her and phone in again speaking to n guy named Marcus, he then tells me that there is no sign of the 5gb that I should get. I ask him what the amount is that I have to pay, he says R291, which was what I paid for my contract, so this can't be right. Then he wanted to transfer me to another dept but the line got dropped once again. This is ridiculous. Your system is no good!!! Either the people who are supposed to update it are not doing their jobs or the program you use is ****!
