Cannot believe Teljoy..

I cannot belief that Teljoy has stoop so low. I have been battling with them now since the 23rd of August. They told me I had to pay in an amount of R 479 that will be my installment for August then they will from September pay amount of R 849 I did that on the 23rd then they deducted an amount of R 927 from my account also on the 23rd I received an sms that this was in error deducted and will be rectified they then only paid back an amount of 644 or 688 and then they took of an amount of 849 on the 26th. I phone and tried to explain that that this is unacceptable the lady kept on telling me that it was in error it will be rectified the next day I waited for the next day but no money was paid back then I spoke to someone in account that kept on yawning in my ear, she put me through to Kwena were I had to explain myself again, she ask me to send through my statement from my bank I did that explaining that my debit order will not be going off because of all these deductions from Teljoy, this carries on till the Friday were she phone me and told me that Teljoy will only be paying 427 and I do not have to pay then for the next month. I lost it because by then my debit order started being rejected. She then said she will request for the full refund to be made. Today when I phone she told me that they are not paying the amount back to my account Teljoy is paid in advance and they will only be paying back the 427. I requested that my debit order is cancelled with Teljoy and then she informed me that now my installment will be going up with R18 because I want to pay by EFT..I cannot belief these companies they do not think about all the bank fees that is now adding up on my account I have to pay for it and it was not my mistake to say sorry is not working for me anymore..I am trying to survive here..So now I am not able to pay my other debit order because of Teljoy..Always spoke about there good service now I think I will never send anyone to them again..and do not belief they will give you R500 for introducing someone that also does not happen!!!!!!!
