Deal of the month 5GB for R99.00

Hi I recieved a Telkom billing invoice stationg that i need to pay an amount of R698.00. First of all this was suppose to be a R99 DEAL how does one get to pay R698.. called their accounts department on the 1st of May and was told that they cannot pick up a bill on theirs side but there should be a huge problem as it can go to a maxed pro rata of around R300, I was advised to call back somewhere after the 5th of May as sometimes it takes time for their billings systems to generate the information.... fast forward to the 5th and am now being told that i have a spend limit of R500. and that i should check my usage rate on page 6 of the bill, boggles my mind because the bill that was sent to me only has 4 pages and mind you page 4 is blank. personally i feel very disgusted in telkom and want out of this deal... but now iam being told that i have to pay a early cancellation fee of R800 and also R99 for the remainder of the contract because it is past seven days cooling off period. i will not recommend Telkom to anybody as what they promise is not what they deliver. *******.
