Disappointing customer Service

Good day, Let me start by saying that I have been with Metrofibre for maybe close to 4 years if not me and I used to sing their praises, but as of late, they are only full of issues and nothing more. On 22 Feb 2022, I called then mailed Metrofibre to advise them that I need to change my debit order date, on 22 Feb 2022, I received a mail from Team 5 acknowledging my request. On 23 March 2022, I got debited as i previously was, this after I changed my debit date and Metrofibre acknowledging the change. Due to no funds in my account, as I was not expecting any debits, the debit bounced, this costs me R115. I mailed MetroFibre on 23 March, no reply, sent a follow up on 24th March, still no reply. I am highly upset and need an explanation as to what happened. Further to this, I am working from home and have continuous internet issues, I have sent mails twice to Tanika Wiggill & Johan Jonker, twice on the same day, 16 Feb 2022, neither of the rep****, it could have been because I did not call through, but they helped me with a previous issue which was also a fault of Metrofibre so I thought it would be easier to get them on mail, no response to date really disappointing service from Metrofibre, if you do not value your customers simply as them to leave.
