Not getting what I am paying for!!

For 5 mnths now I have been trying to find out why it is that i am only receiving a 2 meg line speed when i have been paying for a 4 meg line speed today the issue was finally resolved after many hours wasted on the phone to Telkom to try get someone to assist.,I had to hire my own technician to actually come out and look at the problem he actually spoke to telkom over the phone as I am not IT.Telkom then explained to him that yes I am syncing at a 4 meg line however my account is not a 4 meg line serously if i purchase a car i expect it to come with wheels!! I was told that the account didn't match the line speed so i would need to upgrade my account and pay in 57 rand so i could actually receive a 4 meg line speed. I am so annoyed as when i went into Telkom originally to choose a suitable account for my needs i was offered a 2 meg line uncapped for +-500 rand and i was offered a 4meg uncapped package for 700 because i wanted 4 meg i took the package for 700 what went wrong from telkom side after that i do not no,I would not be surprised if it was done intentionally! Telkom clients please check that you are actually getting what you are paying for go to telkom speed test online.
