Too difficult to debit me

Took contract & insurance 18/12/2015 & was told my insurance would be debited with my contract in January. Only my contract was debited so I called Evelin on ***6 Cell C direct and she told me they don't debit insurance with the contract i must call C insurance. spoke to Portia who referred me back to Cell C direct, told her i spoke to Evelin Cell C direct she said she will investigate & call me back. she didn't so when i called back she and supervisor Charmelle said i must go to the store.went to the Westgate branch and the store manager Ronald told me they have nothing to do with insurance debit orders, he even spoke to C insurance supervisor Charmelle who i must say is very *********** and told her same. She said she will call me back but asked the consultant Magarosi or something to call me to say they will fix the problem and call me back. Today I call speak to Lindiwe who tells me same,debit is going off with my contract, she clearly didn't read the notes. I asked to speak to the manager Rosslyn now Charmelle comes on the line rude & tells me its a general problem they fixed. should i believe her? Lindiwe just said I'm debited since december with the contract
