Pathetic customer service! No one competent to assist!

There was an issue with cancelation in January this year. I placed a month's calender notice but was still billed for the following month although I moved out of the premises.

Afterwards a fee of 1400 was charged for hardware but the hardware was already collected from me from Sky courier services. Now the account has been handed over for a total of R2400.

The company collecting the debt has been calling and messaging my ex boyfriend (not sure how they got his number) whom I haven't spoken to for years. The sms actually states my account details and what I owe (R2400). So next are they going to call and message my employer to disclose this as well?

So is this what customer service with Vox is all about. I was a customer from 2018 and paid my installment of 699 every month yet I could not be assisted when I was moving to a new place. I placed my calendar notice as per the contract terms but I was still billed an extra month, now being charged for hardware which was collected by Vox and now handed over to debt collectors.

Can someone in higher management please contact me to resolve this issue as I have been struggling to resolve this from January?

I have emailed numerous times with no response. I have also called and asked for management to contact me but no resolution or effort to date. It is really frustrating.
