Dissapointed client and unexceptable service

My daughter enrolled at intec in 17 may 2019, person helped her was nelley mbata, paid deposit of R1367 on 30 april 2019. 2 months later after tread messages from intec to pay deposit (after sending proof of payment) she phoned intec but no one could assist her. She then cancelled her course person helped her was jo-ann williams and elizabeth bernard on 18 june 2019. End of june intec deducted a monthly fee from her account. She then phoned intec just to hear that cancelation was not submitted yet. She ask to be transfered to accounts, they but her through to 6 different department but with no luck. She ask to speak to a superior where they refuses to put her through and refuse to listen to her. Intec refuse to pay back her money for she cancelled and did not receive any books or nothing for her course. They send her a invoice for july and going to deduct a monthly fee again. This is unexceptable and we need to sort this out now!
