Supersonic - Terrible customer service

Absolutely terrible customer service from Supersonic. I signed up for Uncapped LTE Promo at R999 per month. At end of Feb 2021 I was triple billed by debit order for ~R3,000. I called in to complain and request a refund on 2nd March 2021, promised that refunds are processed on Fridays. On the same day I sent an email to Supersonic to give 1 month notification to cancel my uncapped LTE product. It is now the 29th March 2021 and I have still not received the refund of ~R2,000. Even worse... I received another duplicated invoice and debit order SMS for a further ~R2,000 payment towards Supersonic.

I have called Supersonic customer support no less than at least 10 times during the month of March. Each time I am told that I need to wait for someone to approve the refund. When I am asked to escalate the matter, or speak to a manager - I am promised a call back, which never happens.

Please do yourself a favour and look towards any other service provider rather than Supersonic.
