Unable to get hold of you

I am desperately trying to get hold of Onair TV for the past four months via all three channels I have available. I don't get any response on WhatsApp or eMail. When I call, I wait forever and eventually the IVR just says "goodbye" and cuts me off? How can it be so difficult to get hold of a company? I was contacted last year for the upgrade deal - something I truly regret. I have NEVER received any contract or statement of accounts. I was under the impression that it's a 12 month contract and tried to get hold of them by the 14th deduction with no success. I then cancelled the debit order with the hope that they will contact me. Now all I get are payment requests and threatening message via email. Please contact me. I want a statement of account and the details of the contract before I make another payment. This is not an unreasonable request.
