Cool ideas not worth having as a internet service provider

We gave notice on the 02.11.2021 of our intention to move from No 24 Orange Road to No 4 Orange Road. We did a request that our line be moved. Today 13. 12.2021 my internet has been suspended as I have not paid for 2 lines. I feel that this is unfair practice for Cool Ideas to expect me to pay for 2 lines when I am only using 1 for which I paid for. I requested for and extention of payment on the line I am not using until the 15th of December and was told that you cannot help there either. So at the end of December 2021 I will give my 30 days notice to cancel my account at the end of January 2022. And look for a different Service provider that will be more accomodating and not hold me to ramdsome for 1 day. I must add that this is the second time this year that I am expected to pay twice for the internet as this happened to me in March 2021 aswell. If this is the way that you want to treat a paying customer so be it
