Unhappy customer

Very very very poor service on the 5th of June 2024 I got a text from Home-Connect telling me that we owed R1369 and I immediately called them to understand why are they saying we on that amount while we made payment of R1369 on the 4th of May 2024 and also we made a payment of R689 for the month of June. I spoke to Siyanda about the incorrect billing which she also said that our billing this month is R698 which we have already paid yesterday and sent pop to *** and she says she has sent an email to billing and will wait for billing to come back to her and she will call me back as soon as billing responds back however she’ll get back to me today before end of business. She then called me at around saying that billing has still not gotten back to her and she will call me the following day which was the 6th of June 2024 and still she didn't get back to until I called home-connect myself after we received another message telling us that we owed R1369 and must make payment I didn't get hold of her apparently she was busy then I left her a message then she called me back to tell me the very same story that billing has not gotten back to her, then she asked me to send pop on their WhatsApp line so that she can fix it on her side while we on the call and then she said that she received the pop and has fixed the issue and we should ignore the messages. Now this morning at 11:21 Home Connect sent a message telling us that our internet is temporarily suspended due to non-payment of R689. They are now not picking up calls and I even had to call a lady by the name of Nikita and I explained everything to her and she asked that I should send her pop on her WhatsApp and I did so at 11:40 and she still hasn't opened the WhatsApp message and she is not picking up my calls either. So we are left without internet while we paid!! Very unprofessional service.
