Bad customer service

I cancel my Fibre after 5 years on the 1 August 2025 with August as my 1 month notice. The agent confirmed that my service will come to an end at on 2 September 2025 and that they will not deduct the monthly subscription. Bearing in mind it took me the whole day on WhatsApp with Webafrica. I do have the transcript. On 1 September the subscription was again deducted from my bank account. After a struggle and argument with the consultant I was advised that my services will come to an end on the 31 October. I've sent the WhatsApp transcript with the confirmation of the 2 September to the consultant but it was ignored. The cherry on the top is I must return the Fibre router to them in-person or by courier. I must say this is the baddest customer service I ever experienced in my life. So I just thought it is necessary for all people with Fibre through Vumatel with Webafrica, don't expect a smooth cancelation process. I will NEVER EVER use Webafrica again.
