Struggling to sign up for a new voice package, very poor communication

I went online under my profile, ordered a desktop phone and a voice package for 278R. I was taken to the payment page where I paid 1020 for the desktop phone using my cheque card, All this happened on the 14th of April. However, your system has a bug and as such my order was not recorded in your online shop. I have sent through my bank statements and have spent 45 minutes worth of airtime waiting for someone to assist me. This is impacting my business negatively in these difficult times. I have sent an email to customer services, Accounts, Operations, Support and still this is issue is pending. I have sent through my bank statements and up to now, still no response. I phoned accounts this afternoon, and my call was transferred to another number where I eventually hung up after 30 minutes.
