******* upgrade as Billing is unware of upgrade

On the 6th of Oct 2015 I was contacted by a person purported to be able to assist with upgrading two of my Cell C contracts. I sent renewal notices confirming the upgrade to take effect on the 1st of Nov 2015. On my November statement the upgrades however did not show and I logged a billing dispute with Cell C with incident number ***. Someone from Cell C called me to say that they will investigate the matter and rectify my Dec 2015 invoice. Yesterday I received my Dec 2015 Invoice with the billing dispute still not resolved. I've logged another Billing dispute and revoke Cell C's debit order authorisation until the matter has been resolved. Today's incident number is ***. I lieu of the aforementioned I believe that the upgrade appears to have been done *******ly and hereby give notice that 2 of my 4 contracts with cell c be cancelled. You are most welcome to contact me Cell C, to resolve the matter.
