EXTREMELY BAD SERVICE!!!!

I in November took out a contract with Mondo. It is now February, and Mondo after cancelling my contract stated "Kindly be advised that we are attempting to make contact with you to advise that your query has been resolved. As per your request, both lines have been successfully terminated with the case number ................... We would like to apologize for any inconvenience caused. Please do not hesitate to contact us should you have any further queries." Of course you would not be able to get hold of me, you cancelled both lines??? I send you an email, as a reply with my home number, and you do not respond????? Then you have the audacity to take money off my account on 31 January 2018 after promising a reimbur*****t due to inconvenience caused??????????? I want my old number back, and expect that someone will come back to me, so over this whole issue. You were informed that I had a daughter in hospital and because of your incompetence I could not get in touch with her for a whole wee****!! I want this matter resolved.....
