PATHETIC customer service and IMPOSSIBLE getting refund for incorrect debit order

After being billed over R1000 what I should have been billed at the end of SEPTEMBER last year, I finally got my refund two days ago and it is the incorrect amount with only R600 paid back to me.

Must be over twenty calls I've had with them over the last three months with nobody knowing what is going on and no way to get into contact with the billing department directly. Was told I'd get a call and SMS from them with the status at least a dozen times as well with this not even happening ONCE.

Now I'm probably going to have to wait another 3 or 4 months for the remaining money.

Would not recommend Supersonic to ANYONE.
