Unauthorized renewal of contract and adding new line.

Cellc renewed a contract and added new line. Since the beginning of September 2023, I received calls from Cellc about specials when my contract expires at end of October. I rejected those offers. I received two of OTP in the morning of 11 October 2023. When I try to call the number to inform them that I did not give a concern or authorization to the request, the telephone number did not work. Since 09:03 I have tried to call 084 135/145/143 without luck. The agent said they couldn't see the transaction. However at 10:40 and 11:05 I received emails with contract information. I went to Cellc shop, they couldn't help to stop the order and delivery. My personal details were also changed such as email address and my contact numbers. I tried calling fruad department, they were unable to cancel l/reverse the order. Instead I was asked to get Police Affidavit, I'd and bank statement. They failed to stop the *****. I was told they cannot anything before I can submit documents. I have submitted those documents. Today no one has called me and nothing is happening. I am not able to taking any contract.
