Unable to purchase fibre voucher and poor contact centre service

For the last 2 days I am unable to purchase a Mitchells Fiber (Vuma Reach) voucher online for some reason. I called in yesterday the 26/08/2020 and a lady advised i needed to be migrated and she would place the order for me on her side and once done i just need to make a payment.

When i logged into my account I can see an order was placed, however it now says error and it does not allow me to make any payment at all. Today the 27/08/2020 i called in twice to your sales department and both times the line dropped for some reason after explaining the situation. This is becoming really frustrating now as it would cost me nothing to just switch over to another ISP.

All i need is assistance with sorting out my account, its not that hard.
