Billing and bad client service

I went to New Zealand from 8 November 2023 to 11 March 2024 to visit my kids. I stopped the subscription for the time which would be 4 months. I However had to give 1 month notice, so could only cancel for 3 months. I thus paid them for 1 month for now services. Then, when I arrived back, I had to pay nearly R500 to reconnect as if it was cancelled due to bad payment? I never paid late because it is on a debit order. In the mean time they offered vouchers/Prices for people who wanted to reconnect. So, I get punished with R500 for the fact that I reconnect. This is, to my opinion, an insult to their faithful clients. I slap in the face... THIS business is very clever with feedback: reported to Hellopeter.com that they will solve the problem directly with me (not to post their comments on social platform - why not?). The a lady left a message on my phone to reply on her email. After a week NO EMAIL was received from them, neither feedback, nor any phone calls. THIS CONFIRM EXACTLY WHAT I SAY: They don't bother with client service as long as they just can get your money, it seems. They are NOT transparent.
