VUMA OR TELKOM???

I have just been on the phone with both Telkom an Vumatel, we have a 20mb line which is being paid for but only supp**** 4mb. Shocking as our payments are done on time every month. The inconvenience means that we thus need to also purchase data bundles which are expensive also thereby contributing to how much we spend in total every month. Do not like the fact that the blame is shifted from one place to another. Wonder if the two providers ever thought about have one system that would work. Telkom says it's Vumatel and Vumatel says it's Telkom. There's not even any way we can lodge a complaint about this except via this medium. Frustrated and disappointing.
