Dear Sir or Madam,
I already sent my all documents for cancellation +my plane ticket+I paid basic fee of three months at December 2019 but O2 is still asking me to pay 86,07 Euro. Why you are not canceling my account from October? I don't want to pay money because I don't use it anymore and I already sent every documents plus closing fee at December by post. Can you check my account and send me mail?. I am at Turkey from October and not using by O2 account from October but you are still asking me to pay money. Please consider my request and check your mails and posts.
Best Regards.
