Bad service

I was approached by an account manager Jack Poussard on 20/06 and offered 420 hrs.I went through the registration process and could not pay registration fee and requested a callback. Jack Poussard emailed me constantly during this time and after looking into the brochure I realised I wanted 500 hrs as I would have a better advantage. I advised Jack Poussard on the same on 28/06 .I enrolled with a link he send and when I was required to pay it asked double the registration and I asked him if it was correct and he confirmed it was .After accessing my online account I emailed Jack Poussard on 03/07 to advise that I have been enrolled for both courses , he denied assisting me but promised to forward it to customer support .On 19/07 I received SMS from my bank with regards to failed direct debits,I couldn't understand as I was not due a debit order and after some time I logged into itoi account to notice they had an unpaid amount R1268 which was not agreed.i also saw that the 420 hrs was never cancelled both courses have the same material however 500 hrs had extra modules. I am very upset and charged R10*2 per day for 15 day which is R300 in bank charges as they debited incorrectly . I've phoned them emailed them and wow it is so hard to get this sorted .I want immediate cancellation and reimbursed for my bank charges. I have all the emails from Jack and myself with what we discussed and as their calls are recorded Jack called me on 28/06 to assist with the enrollment
