No feedback on so-called Black Friday Deal

I have been a loyal Telkom customer for years now. My mobile contract is due for an upgrade this month. I app**** early on Black Friday for one of the advertised deals, to upgrade my contract.

Until now, I haven't received feedback on my order request, despite having complained on social media, and told that my complaint has been escalated. The 'sales' department claims that there is no stock of the deal, and cannot say when there will be stock. The same thing has happened with Telkom's Black Friday deals before - no stock, no feedback.

My contract expires in a few days, and if this is the lack of service given to a long-time customer, I'll take my business elsewhere.
