Webafrika bad service

WebAfrika is useless. I have no internet for 2 months from 3 October. There is no email or contact to speak to. they anther transfer you to WhatsApp, then end up talk to a computer. the bit of times someone assist me on phone, they lock calls for reference, then promise someone will call back. No feedback of call back. after 2 month with calls and whatsapp with not solving the problem, I go online and cancel my contract. then they call and ask for a second change. they send out a technician. he said everything is fine. then said they they will refund my 2 month. 2 days later my internet still not working. 19 November. i talk to someone on whatsapp. takeabout all Sunday from my time, with whatsapp up and down, he realise my rooter in folty. he lock a call again to refund my money and replace my rooter. the 23t November they deliver a rooter at my work. still no refund or feedback. I block and cancel my bank card at my bank. they had to send me a new card to make sure they will not deduct anything from me. 2th December they deduct R739 again. decline course i block my card, 4th Dec they deduct again. i had to reverse at my bank. still, nobody calls me. I phone yesterday and today again and leave my number. please help me to solve my issue. what does I need to do. its really draining.
