Poor service attendance

I have the fibre with Vox, ichanged the apartment in December 2022, january i have been trying to contact the call centre with no luck the answering machines goes to 1 option to another wich i did press all of them n hangs up, february i got th rep in th name of nonhlanhla, she said within 5-7 days th technicians wil come ,that was in first week february, today its 20 march, nothing happened. I decided to reverse my January and february 2023 debit order, within two days thy noticed and sent me email to pay up, but money thy do notice, the service( network) which has been off for three months is not noticed, is it fair on th customer, may th services be cancelled for good. M not happy at all.
