On Air are *****s

I ordered the On Air deal for the SD PVR swap out at R79 permonth over 24 months. The decoders were only delivered 3 weeks after the telephone acceptance, when it was said it would take 5 to 10 days. On delivery of the decoders on 2017/11/28, I called a few installers in Cape Town and none wanted to assist saying On Air "does not pay". I immediately called to cancel the contract and for them to collect the decoders. On 2017/11/29 I called and was transferred to the cancellations department where a lady told me she will log the cancellation and get RAM couriers to collect the decoders within 10 days and nothing will be activated, the call centre agent said that as long as the decoders were collected before 24 December 2017 no debit will go off. Later that day i get and SMS saying the account has been activated. 2017/11/30 at 08h12 I spoke to Christine who said she can't help me because their systems are down and the manager Kershan Pillay does not take calls. They do not give written confirmation of activation or cancellation via email, only via SMS, of which I did not get a cancellation SMS. I get the feeling the decoders will not be collected and they will hold me accountable fr the contract when they cannot provide the full service including the installation. Their website says they are responsible for the installation.
