Vodacom Fibre

I can for the life of me not fathom the in efficiency of of Vodacom technical staff. I have sent more than 170 screen shots of my fibre line. They always send a work number which states they are working on the problem. They close the number before fixing the problem. So I log another query with the exact same result!! The problem is as follows: I pay for and have a 20mbs download with a 10mbs upload line installed. The problem is that I receive 10mbs upload and 20mbs per second upload. All that needs to be done is to transpose the line and everything will be hunky dory. But no it seems as if they are incapable of understanding the problem. I cannot wait for the end of April when i can cancel my contract and move to a service provider that has more capabilities than Vodacom Fibre. I am loyal Vodacom customer since 1997.
