Will NEVER reccomend Telkom to anyone

I app**** for a Telkom laptop package at the V&A branch. This took multiple visits as the advertising brochure and staff were not totally clued up on the specifications of the different laptops being offered. In the application form which I completed, it stipulated a 24 month contract and also a maximum monthly debit. The Telkom brochures advertise the various packages as a 24 month, with 24 equal monthly payments. I received a phone call that my application had been approved and that I had 48 hours to collect it or I would have to wait for another one to be ordered for me. I went to collect my package in the last few days of the month. When I went to collect it, I was informed that only my laptop and Microsoft Office were ready for me and that I had to return again to collect my router/sim card. The first invoice I received was for 3 full monthly installments for the laptop, 2 full monthly installments for the router/internet and a 3rd one for the router/internet for the last few days of the 1st month. At no point during all of my visits did anyone inform I would be paying 3 months in one. Based on the Telkom advertising and staff I was taking out a 24 month contract with 24 monthly payments. When I complained to them I was told to complain to Feathercom directly who owns and manages the shop. The staff passed on my complaints but nothing was done. Apparently Feathercom tried to contact me but I found no email or messages on my phone. After multiple enquiries over a few weeks at the V&A branch (I have been informed that Feathercom Management/staff visit the store weekly) I contacted them directly. I found Feathercom to be unprofessional, badly trained staff, uncaring, useless and very far from being customer focused. The V&A branch staff were very polite and tried very to go the extra mile, but the senior management it seems are a different kettle of fish. I was informed that they directed my complaint to Telkom. Telkom informed them that nothing could be done. This was roughly a month after I collected my package. When they eventually did reply, their response to me was to email me a copy of my acceptance of the package and a very weak excuse for an apology. The Telkom advertising is misleading and staff appear to not be trained correctly or sufficiently. If I signed a legally binding document including a maximum monthly debit order and period of time is it not binding? Even the advertising or conditions on the brochure does not state that 1st month billing is 3 months.
