Telkom's Unusable Computer System

I have a LTE rooter and a data contract with Telkom. During lockdown, we needed more data and therfore I logged in Telkom's website (I am a registered member) and requested an additional recurring data bundle. I did receive this bundle once and therefor Telkom did charge it on my bill (which is correct). I was upset the following 4 months, because not once did I receive an additional bundle, although Telkom kept charging me for that. Yesterday I went to a Telkom shop and they agreed that I did not received additional bundles, although I was charged for 5 months for an additional bundle. I asked them to remove the recurring data bundle from my account and they battled more than 30 minutes to try to delete the recurring bundle, but without success. I did not want to cancell my data contracts, but unfortunately I had to do this, because I cannot afford to pay for something which I do not receive. The Telkom staff were very helpful, but unfortunately, helpfulness means nothing, when they have to work with a system that is not in working condition. I took out a Vodacom data contract, a few hours after I left the Telkom shop
