REPETETIVE REQUEST FOR UPGRADE FROM 20G TO 50G

App**** mid July for an upgrade on 20G CAPS to 50G on my landline number ***. Assumed it was done until I run out of DATA within 2 weeks. I phoned (10210) (about mid-August) and the assistent told me they will fix it, but there were problems with the internet system of Telkom. She will phone the next day. Nobody phoned the Wednesday. I phoned the Thursday again and nobody could assist me properly and told me the same story as the first assistent. On Friday I phoned again. The guy tried his utmost to help me but the line cut off after about 45 minutes. On the Monday I phone. There was an error on the line which they don't know how to solve. The lady would pend the request for 50G data and it will be increased as soon as the network was up and running again, because there were still problems with the network. Nothing happend. 21 Sept I phoned. THe assistent told me that an error showed on my account and she doesn't know the reason. She phoned a technician and he could not help either and the lady doesnt know what to do or cannot recommend a solution. I am fed up!
