Service Level Agreement not met as informed in writing.

I placed an order for Rain 5G on 18/03/2020. Order confirmation confirmed delivery between 1 - 3 days. Followed up on Friday, 20/03/2020, day 3, with an e-mail to customer support, also by waiting in a chat queue, only to have a consultant, Wayne, inform me that he will let me know once logistics has rep****- still awaiting his feedback. Followed up on Monday, 23/03/2020, day 4, as they only count business days, the consultant informed me that delivery should be on Monday, but has e-mailed logistics, will update me once a reply is received- still awaiting feedback. Followed up, via a telephone call on Tuesday, 24/03/2020, only to have the call disconnected after 1 hour on hold. Now I am again waiting in the queue for the live chat, currently position 101 in the queue. Rain took my R999.00 on Wednesday last week and I still have no feedback, even after me making the effort to find out when I can expect delivery. Another R999.00 is scheduled to be paid on 01/04/2020.
