WRONG AMOUNT DEBITTED AGAIN!!!

On 29 jan 2016 I was debited with R1431.00 of my account. Should be R399.00 per month. Today 15 Feb 2016 debited with R1140.00 ... What is this . The 081180 nr does not work as well so it is pointless to sort this out in any way telephonically. Clearly there is no training given to these people to do there job correctly. I have been going to fourways mall Telkom store numerous times over and over. Eventualy a man by the name of trevor at the call centre reinstated a new line for the 20gig contract. What is these amounts going off my account now all of a sudden? I Got an email yesterday from telkoms so called tech team that they tried to contact me. No one ever since I am fighting since last year September has been phoning me back. I left the amount of R1431.00 but will not do the same with the 1140 . it will be reversed. If I get no real response from anyone within the next 24 hours I will proceed to telkoms head office. Money does not grow on my back and I am not responsible for these amounts. R399.00 only pm for 20gig plus 2 multi sims. Check this and sort out
