Teljoy Rental Payment Notification

I am highly perturbed by the service received from Teljoy recently, i still await a call back from the supervisor/manager regarding my account. Cindy from the accounts department whom i was communicating with after i urgently needed to escalate my query is still returning my call after she would have supposedly listened into the recorded conversation between myself and her colleague. I am now inundated with messages saying my payment is due. I refuse to make any further payments against the unit until i receive a call back from a senior manager at Teljoy. I stem from the service industry with over 20 years collective experience in various industries, however the plight remains the same, service is spoken in a universal language which pertains to adhering to simple processes and communication. I refuse for my name to be *****ed or blacklisted by the non compliance of the employees who are supposed to be in the service industry.
