Home-Connect extremely poor accounting service

Home-Connect informed me at the beginning of 2024 that they will upgrade my line from a 250/250 to 400/400 with a price increase. I was told that could not stay on the 250/250 since the package was discontinued, so I downgraded to a 240/120 line on 1 March 2024 @ a monthly rate of R898. Then on 1 March 2025 they started charging me for a 400/400 line @ a rate of R1268. Trying to get this resolved is impossible. The number of calls and time I have spent to get it resolved is mind blowing. You cannot speak to a manager or someone in the accounts department since each time you get connected to an agent (having to repeatedly explain myself) they log a case and say that someone will call back. The cherry on top - I continued to pay my normal R898 via eft and they still deducted R1268 via debit order (I want a refund) I never experienced such poor service previously from Home-Connect but maybe it is time to look for an alternative ISP.
