Telkom Vumatel fiber disappointment

Good day, On 17 August I app**** online on the Telkom site to have our current 20Mbs/2Mbps Vumatel line upgraded to a 50Mbs/50Mbps line. On 19 August 2020 I followed up on the progress of the order only to find out that the order has been cancelled for no reason. I then had to place the order again and this time it seemed successfull when I followed up the same day. I then waited 7 days and followed up with the upgraded department on 26 August 2020. I was told that the line has been successfully upgraded to a 50Mbs/50Mbps line. I did a speedtest only to find that the only thing they upgraded was the upload speed from 2Mbps to 20Mbps but my order was for an upgrade from 20Mbs/2Mbps to 50Mbs/50Mbps. I have now followed up twice only to be told that the error has been escalated. My question is therefore, even though I have not been fully upgraded yet am I now already being charged for a 50Mbs/50Mbps line even though I am running on a 20Mbs/20Mbps line. Why was this not done correctly in the first place and when is this going to be reolved or should I rather cancel and find anotyher service provider? My 2 reference nrs are: *** & ***9.
