Inconsistency on important aspects that is Telkom

Last week, I found myself excited to join the ADSL world & get myself some Internet, after much searching, I thought that Telkom would be the most credible institution to join. I contacted the Call Centre & spoke to a lovely lady who explained the packages & I picked the one best suited to me at R579 uncapped 2mb line. She explained that installation is free & that no other charges would ensue. Only to get an SMS to advise that I'm required to pay a R700 to secure my installation, by this point I was upset, & called to confirm what this was. Again, a kind gentleman explained the need for this charge & I understood but found myself more upset that this was not advised to me sooner so I'll be prepared for it. Today I went to pay the R700 and was advised that the monthly subscription is no longer R579, but R609 since the 1st August. I CALLED LAST WEEK! that was the 12th August, 12 days since the first & was still quoted R579, Why? Then the lady at the Telkom Direct Store in Century City (where I paid the R700) told me that I might get double charged on my first subscription payment as there are extra charges involved. I am peeved and am fully prepared to cancel without even starting,
