Vodacom unprofessionalism HELP

Came in to pay my account on vodacom in store...delt with a trainee...gave my cell number and the incorrect number was taken down....the account was paid to my deseased father's account that we took 1 years to close. So I asked for it to be allocated to the correct account...I was told by the manager on duty MC cotzee who had a terrible attitude and stored off while I was speaking to him and he stated he does not have time for this....I mean is this what a company that we have been with for over 22 years treats their customers...the number I gave is for a number I use daily to drive my work...now this will eventually shut down because of none payment I cannot afford another payment...I just wish vodacom can help me here and correct their attitude.
