Disappointed paying customer

I have been mislead thinking your 30 Mbps line was still available, this was 26 February 2025 ,I had to cancel my 20 mbps this is when my hell started , I have been trying to get a new reference number since Saturday the 1 March 2025 until now the 5 March 2025 I am still struggling, when I have called to cancel my Webafrica wifi account the agent hangs up the phone this has happened 3 times thus far 3 call centre agents have hung up the phone while I was talking to them about cancelling my Webafrica account. I am saddened by the service of Webafrica and also we have to wait four hours for resolve on WhatsApp chat and also the phone line on Webafrica is not clear at all.
