Bad Service- Refund not happening

It is so funny how companies, in this case, Telkom, are right on time to deduct/take their d/o every month, then to penalise you or even cut your line, when payments are late, but when if comes to them returning excess money, as in my case, they don't. When I app**** for a refund, as my contract term came to an end, they told me, it would take 7-10 days.... It's 2 months already! You don't get hold of anyone on their phone lines, or no one responds online or on the chat line, and when you go to their branches, you wait for hrs. I know it's lockdown and all, but your turnaround time sucks! It's been 2 months and I haven't heard from anyone! I want, No, I NEED my money back, please? "Your query will be attended to.Your case number is ***8" Thank you
