Worst service, passing the bucket excuse

Good day

Please note that I am not liable for premiums from September 2021 because of the following reasons. I never received communication about my contract expiring in August I never received statements from Sept until now I never agreed to month to month billing/cover In August I sent an email to *** to ask about my premiums but received no feedback Why was the device not changed if I was supposed to continue with the contract ( Is that not supposed to be done) Your legal department keeps blaming the retentions department, and how is that my fault? Your billings department fails to investigate whether the client has been informed of changes before even initiation the billing. In addition NO communication was sent with regards to changes in my debit order amount. I have a contract with MTN and they have called me that my contract expires in January 2022 and premiums will be reduced effective November. WHY CANT NETSTAR DO THE SAME AS A SERVICE PROVIDER?? I do not want to continue with the contract because your service is very poor, therefore I am not liable for the premiums from September 2021 going forward.
