Bad service/False Billing/Lack of Communication

When I registered with Intec the consultant was very helpful and Intec was in constant communication with me. After the registration was complete thats were the problems started.

I have registered to finalize my grade , the only done was to the USB thats the part intec played and I struggle to register with department of education and the process I was asking them for information. by the time I get the information the registration was almost done, the subject I have registered for were not available at the high school and for sylabus registered I have informed Intec that I wish to cancel because the services that I registered for are not useful hence when I got to the high school I found different things.

I also advice them that I will pay for what was done but to cancel the rest, but they have pretended that they dont get my communication I have explained this to 4 different call centre claiming they are calling from Intec each of the call I have to start explaining by doing so they want months to pass so that I can be liable for payment.

I have sent an e-mail to the consultant that was assisting he never rep**** I was advised to send to a cancellation e-mail I did that but still getting email/calls for demand of payment none of the people claiming not to have received my communication how so? the same contact I have used to register where they were responding all of a sudden they dont get my communication. I feel this is the way of sucking the money from me to pretend that I'm not in communication with this is absolutely not fair.
