slow response, slow service

when i first signed up at vox long ago, service was great and fast, now its just gone completely opposite. It started out by me signing up for a 1mbps uncapped combo, i initially wanted a higher line but i thought i would trial vox out first, despite many telkom issues already which has made me fed up on it's own, vox service was great until a while back, now i decided ok lets upgrade the line 1 higher and see how that goes, 10 days ago i called and processed the upgrade - the agent didn't give me any time frame and said its processed, i accepted the quotes, etc. i then called vox the next day and another agent told me "no, it will take at least 3-4 days" which i already knew is a bunch of bs cause i am in IT tech and do upgrades all the time for my clients, it takes 3-24 hours, with the worst case i have ever seen taking 48 hours, but OK i waited patiently. I then wrote tickets and more tickets, each time i just get a generic response "we are waiting on telkom" or even just a simple response as "you are writing duplicate tickets" instead of actually addressing my issue, which fine i understand, then 7 days later i finally get feedback that they are trying to find out what is the hold up on my upgrade, and that the telkom guy "Andre" will respond and then i will get feedback, 3 days later i have gotten no feedback, i then call today again, i get the same generic response that it is "telkom" yet vox takes absolutely 0 effort in getting my line sorted either wether its telkom's fault or not, they claim they "deal with telkom on your behalf". I am only thankful i stuck to small lines due to past bad experiences. anyway, i am at the point of canceling the line altogether if this is not sorted within a few days.
