Bad Bad Bad Telkom

I took out a Telkom wi-fi contract in August of 2022. The date for the debit order is every month on the 5th. From the start, the router did not work correctly. I reported it several times, but no one could resolve the issue. Furthermore, the debit order only goes off every second month, Telkom's only answer to this was that the computer does it, and they cannot change anything about it. My account went into arrears since they debit my account at any time, even on the 20th of the month, after I indicated it should be on the 5th. I made the payment for the arrear amount more than a week ago, and until now, my service had not been restored. The contract stated that it is 10GB during the day and 10GB during the night, I never receive this, I have to buy data now, I do not use the data for games or streaming, only for receiving Whatsapp and sometimes some Facebook-browsing.
