Frustrated by Telkom

I app**** for a Telkom router online and they delivered on the 23rd Sept 2020 I realized that it's the wrong router as I specifically wanted the mobile one . On the 25th Sept I called their callcentre and was advised to do a cancelation by a guy named Steven which I did cancel and was told that within 72 working hours the router will be collected but still today no1 has collected it. I have been calling their callcentre when they do decide answer their calls usually after more that 40 minutes on hold they would tell me different information. I have been advised that they will debit my acc even though I cancelled within the cool off period (7days) which I find absolutely ridiculous since I did everything right as a customer and they failed to collect the router , another agent told me that it was my responsibility to call the courier company to come and collect after I wasn't satisfied with the package , and another agent dropped the call whilst we were talking. Telkom does not know how to treat their customers and I'm so frustrated I just need them to come COLLECT THEIR ROUTER!!!!
