Unable to cancel a mere order!

Been struggling for past 3 weeks to cancel my order for fibre. Am therefore unable to proceed with any other ISP. Went in to a store, phoned in to the call centre, even escalated to the "CEO Hotline" but incompetence is evident in all their departments. My daily calls are met by new and 'improved' reasons as to why my order is still active on the Openserve portal: the voice line reserved for me is still on reserve status; there's yet another system that the order has to be cancelled on, etc. Each time it gets escalated to an 'IT' department- they're not allowed to say which IT dept or to who, there's no SLA and even if there is, there's no adhering to it. I've spoken to every agent on the CEO Hotline, several times, explaining the case each time: Vuyo, Nomzikazi, Aviwe, Nolu, Sibulele, etc. Been escalated to a Candy, a Zach, a Clint, a Nonkululeko, a Keenan... is there not a single competent person in Telkom? Or anyone willing to work? All I need is for my order to be cancelled, it's just an order. Hadn't even been installed. Complete FUL L cancellation, on ALL of your systems! Wake up Telkom! Your "CEO Hotline" is a front for pathetic service!
