Complaints of no service from Impaq Education

I am an existing learner at Impaq education, since 2016. From the 4 January 2019, I have been trying to call them, I was on hold twice that day. Then on the 7 January 2019, I phoned and was on hold again twice between 20-30 minutes, in addition I filled out a form on their website to inform them of my enquiry, as well as sending them two emails, informing them of my wasted calls and the matter that needs assistance , one of which doesn’t work anymore yet it is stated that, that email is especially for FET students. No response was received from those emails. Today on the 8 January 2019, I sent another email informing them of the matter in need of assistance, and I was on hold yet again for another 28 minutes. I then sent another email, and still no response.
