Lack of service and feedback on new business

I app**** for the double deal new contract deal. I was requested to send bank statements, payslip and id. Which i have done on the same day since Monday i am the one continously following up with the progress the feedback i will get is that the supporting documents has been submitted to the back office and they are waiting for feedback. Today i eventually got hold of the agent by the name of Bronwyn still telling me they are waiting for back office but now they want my 3 month bank statement individually for each month. Not even 1 courtesy follow up from Vodacoms side and when i eventually get feedback its we need more info after a week. Im truly disgusted with this level of service.
