CELL-C LACK OF COMMUNICATION

I am an exisiting cell C client and app**** for a new contract line last wednesday . The consultant told me i was approved and the validation department will make contact with me. On Thursday 14/12 i was called 4 times at around 11:00am within a minute apart, not even allowing a 30-minute break between call back. I was in a meeting, I tried calling back 3 times to customer care department and was transferred from department to department no assistances. I eventually was advised to wait for their call, still No response. I called back this morning 18/12 now I'm told if they need anything they will call back as my contract hasn’t been approved as yet, I was promised by the sales consultants my phone should be delivered by Wednesday 20th December as i mentioned i am going away. Imagine apply for a new line with cell c is so difficult, what kind of service will i receive. At least let me know what's going on or alternately i can take my business elsewhere.
