Complete incompetence

How many times should one cancel a contract to ACTUALLY get your request processed and your contracts cancelled!!! After calling in April and requsting a cancellation, I followed up on 1 May as my contract was still not cancelled. Then on 1 May 2015, again I gave notice and request my 2 contracts to be cancelled due to being extremely tired of this apparent service provider's utterly disgusting service. Then on 16 June, I went to the Clearwater Mall store to go and cancel my contract yet AGAIN and to ensure that this time it is done. My contract was then to be cancelled on 17 July 29015 after my 30 days notice passed for the 2nd time. Today I yet again take time and call Virgin Mobile to just get confirmation of what I already knew - THEY DID NOT CANCEL MY CONTRACTS AND I STILL NEED TO CONTINOUSLY FIGHT AND STRUGGLE TO GET MY REASONABLE REQUEST PROCESSED. I want a Manager to call me and explain how long I should expect this request to take before my contract are cancelled with immediate effect?!
