Service cancelled, but not properly actions by AN

(Perhaps this matter will be finally resolved if it is lodged through this forum...)<br> I was an Altech Netstar (AN) client for approximately 7 years, never missed a payment. <br> Timeline: <br> - Notice of termination of service: 18 Nov 2014<br> - Follow-up due to no response form AN: 02 Dec 2014<br> - First response from AN (23 days later): 10 Dec 2014, stating cancellation is subject to 30 days' notice<br> I accept the requisite 30 days' notice, but notice starts to run on the date of first notice given. Therefore, had AN actioned the request so sent initially in November, the service and my obligation to pay would have come to an end on 17 December 2014 already, and AN actually owes me a credit.<br> After almost a year, I still receive statements, invoices and SMSs for a months' service fee. I will not be held accountable or be bul**** or penalised for AN's sluggish responses and failure to process a cancellation notice.<br> I have corresponded with various individuals from the Customer Services department, all to no avail.<br> I require a statement reflecting a ZERO balance, and a written confirmation that the matter is formally resolved.<br> All my rights shall remain strictly reserved.
