Very poor service

I bought airtime in June 2020 from my Capitec account for the amount of R301 and divert it to data to download the software of 3G, Telkom still billed me on my contract account. I 've send several e-mails and statements but still no money we refunded. I have endless problems with Telkom because their call center does not answer their calls.and if they eventually after 30 min, they escalate to their accounts department to this e-mail address - *** dont even reply to my e-mails anymore. It is October and i'm still waiting for my refund. Very poor service.
