Complain About Unresponsiveness and unprofessionalism and very bad customer service or no service at all

Very unprofessional and uncaring, customer service does not exist very unresponsive for instance I will pay month end and they will disconnect me without asking for a proof of payment from me or inform I have to let them or send them a proof of payment when I have paid. Their wifi is so slow and have disconnected me since 16 Tuesday May 2023 without any reason because I have paid for May month I have emailing and whatsaap them to no response, very unsatisfied and unhappy because I am not being rendered the services I paid and no one is attending to me.
