Not willing to refund, due to admin error

Please tell me why are you STILL billing me for a cancelled product?<br> This product was cancelled in April. Reactivated by WebAfrica for no reason and now you are trying to take payments from my account?<br> The call center confirms that the product has been cancelled. Your billing department says its not. No one on the phone can seem to help me. Your online chat keeps asking me to log tickets. I have logged them and they keep being closed.<br> Tell me why you have all these ways from me to get in touch with you but so reluctant to clear up this issue?<br> <br> After lodging about 5 tickets, numerous live chats I finally got a call from your billing department. She confirmed to me that it was an admin error. She also stated that the initial refund which I was promised due to this error cannot be processed and now I need to pay. <br> <br> Please clarify to me why I need to pay you for your employees errors? I have no problem with paying this account if I was going to use any of the services. I did however follow the proper channels to cancel this product.<br> <br> Please get back to me as I cannot seem to get through from your call center to someone that is willing to help
