Extremely Dissapointed

I have been doing my research on Impaq homeschooling or online options. I did the registration and my books were to be delivered. When I did the registration, I ordered student pack and facilitator guides, but only to be told by the Homeschooling facility that I just need the student pack. That is when I reaches out to the Impaq assistants to request that I cancel the facilitator guides. It seems they were already on the way, so I therefore requested that I return the facilitator guides as I do not need them. It took the almost 10 days to come back to me. I have reached out on their WhatsApp number on several occasions and did not receive any response. Eventually I had to take the books to my sons school as he was falling behind. Eventually they sent me the cancelation forms, but now they say I need to return ALL material and re-register. It's the 6th of Feb, how long was I to wait with my son not using the books. When they could not even respond and their contact number not going through. I am EXTREMELY Dissapointed at their customer service. And need an intervention. I am in the position of physically returning the facilitator guides, but I cannot return the student package because they at the Academy and have been used. I need to be contacted asap for this to be resolved
