Useless incompetance

The contract, 5Gb Lte data bundle with wi fi router capeable of 150 mb/s. So now I have a very fast router that flounders along at a couple of hundred bytes to four hundred kilobytes per second. No trace of the socalled Lte for which I'm paying. This month Vodacom decided that I don't need any data but they still need my payment. Writing to them got me a mail requesting my personal information. Why not just recharge my account with the data I have paid for? How about delivering the promissed speed we have to pay the international highest prices for. This new South African way of doing bussiness is total *******. We have the most expensive service providers worldwide yet we recieve the slowest and worst possible service.
