Bad business practice

I entered into a contract via an agency called buymondo that markets routers for Telkom and in it there was a router that comes with a 2 daily+2 night owl data bundle for only R149 a month. I requested a statement each month and a contract stipulating what I am paying for as my data consumption plus a recording of the conversation of an agreement with the sales lady ata the agency. I was told that the contract is with the Telkom and not them and they can't help me with my problems . I contacted Dylan on his email ********** as well as calling this number ********** which appears to be the customer service number with no assistance for their customers and this email as well ********** . Debit orders are not as agreed and there's no statement coming and I had no contract as well as copy of the recording as I requested.my data charges are high and it is cut as I speak which nobody answers my calls when I call but all the line speaks about is endless technical errors or problems which do not get solved. I also sent an email to ********** to escalate my problem but never got responded and even the local branches one at wonderland once put me on a call which had no answer and the lady said that they cannot help me with anything then. I am currently filling the matter with icasa and national consumer commission which I hope that I will get clarity on. I am charged more than a thousand and five hundred and sometimes a thousand monthly not knowing what data I used. I now parked their router which has no use to me..whoever sales lady who got credit for incomplete service at my expense I hope she loses a job for that as she could not do her job accordingly..she never checked on whether I got what she processed for me and worse they cannot retrieve the documentation on the system but they punched in my info and the excuse is "my details are with Telkom and they cannot do anything I should call Telkom"which I can't find. I am extremely angry with what they gave me.

If there's anything somebody knows that I might do to correct this *********** business practices in this well known businesses please share. Contact: 073****366
