Unhappy customer service whereas I have paid my account but it was suspended for no reason

I have been without internet connection since the 10 June 2025. I have tried to send WhatsApp several times to no response. I have called plenty of times to no answer,or the phone is just ended with no response. I have sent plenty of emails and I was only responded once whereby they requested proof of payments. I have sent them but my internet connection is still suspended and I have been paying and have paid for my account in full and I am not in any arrears. I am so frustrated with the incompetence and the level of unprofessionalism that I have experienced. I am still without internet connection and no one from accounts/support/sales/is of assistance. I am deprived of the service that I have paid and have forwarded proof to accounts email several times with no response. This is the worst fibre service I have ever come across especially with my account up to date but my services have been suspended.
