Vodafone Nodal calls only to repeat what they have already stated before

Despite my repeated requests to have only written communication, Nodal office called me today only to repeat what they have been saying all along i.e their system says that the updated documents were not received and so they decided to deactivate my number which is absolutely false. I did submit the updated documents but their staff did not update that information on the system. According to them, the store concerned declined to comment. I have reminded them that an investigation has to take place for the truth to be uncovered and a written apology letter has to be sent out to me for wrongfully deactivating my number and causing such great harassment as well without their finding out the facts.My case stands open !
