Worst Customer Service Ever from Supersonic

I just received an sms notifying me that supersonic will be deducting R1 519.36 from my account for July.

I was debited R813.57 on the 25th June 2020(i provided proof)

I called the call centre (held on for 30 minutes), Anele from the call centre informed me that according to their system, there is no proof of the debit For June.

I asked them to provide an explanation for this as the debit order that I’m supposed to be paying is R795 as per the invoice i received as well as confirmed to me by Supersonic agents. This was on the 25th of July

After 4 days of waiting and sending Supersonic follow up emails on a daily bases I receive an email for one of their administrator ( Mariska Swabey) on the 31st of August

the email was vague and does not even explain what has happened. the administrator talks about an overcharge being processed (dont know what they mean by this . Then she speaks of an amount of R940.20 now being due.

To my calculation 1519.36 - 940.20 = 579.16. I was debited R813.57 in June 2020. How do Supersonic then decide that i owe R940.20 ?????

Mariska Swabey provided no explanation as to why i need to pay that amount I have requested that they call me to explain what had happened.

The invoice I received clearly states that my 20/20 line is R795. How have you thumbsucked this amount of R940.20

I have since sent this query to 3 other people within Supersonic on the 5th of August and still no one is willing to assist or even respond back to my query.

I followed up again on the 7th of August because no one is getting back to me.

On the 7th of August Mariska Swabey finally responded and said that she is escalating this to the sales team manager by the name Johan Engelbrecht ( i dont know why because this is clearly a billing mistake).

It is now the 11th August (18 days since my initial email). All i receive every now and then is "apologies for the delay" yet no resolution.

There is still no response regarding my query. I have yet to receive a phone call. I have been requesting for a phone call repeatedly and I am still requesting it.

Even when issues get escalated, the level of service Supersonic gives is **********

I take their constant silence from Supersonic as an indication that they dont need me as a client anymore
