Cell no Deleted

My Fiance, was without work. We paid the account bit by bit what we could afford. We received an sms to say that Vodacom will assist with a discount. Wie needed to call ***. when calling this no the cell no in question was deleted. we paid money's but now no-one can trace the account or even anything relating to the no. She has spoken to a Vodacom team member in September to give consent I can call on her behalf, but with the no being deleted, there is no notes to confirm anything on the account. they were asked to call her today between 12 & 2, but the time is now 15:00 and no vodacom member has contacted her. if the account is deleted without her knowledge, please pay back the monies we have paid as there is no account to be credited. please can someone call me after 17:00 as we work in call centres.
