Questionable company, substandard service

Tower3 aka Rogue Telecom: I have been a client for over 3 years. Invoices are issued earlier and earlier each month. There are multiple bank accounts specified for payments. The company cannot be reached via their published landline. Accounts cannot be reached directly, nor can technical support. Months later I am still waiting for the PR representative, Shandre van der Westhuizen to return my multiple calls and callback requests. I pay every month on time - earlier than the specified date. The accounts department does not reconcile their payments received to the clients' account. I have made a payment in Sept using a previous reference. Accounts dept is unable to see the payment and identify that the client has paid using a previous reference. Without notifiying the client that they are missing a payment many months down the line, they suddendly cut a client off unannounced. No apologies. Only Johan Botha saying "It's not our job to reconcile payments received to clients accounts". Afraid I'm unsure of whose responsibility it is other than yours? They charge double the price for less than half the service. Since my initial review, they have also elected to no longer issue me with monthly invoices. I have paid my monthly service fee and requested that Shandre issue me with an invoice with a zero balance. She has also chosen not to respond to my messages nor provide me with the requested invoice.
