Landline/ADSL still not installed. Deposit paid

I app**** for a Telkom landline and Telkom ADSL on the 13th of August 2015. I have already paid a deposit of R700 but to date I have not received service. I have called the helpdesk twice in the past 2 days and am being told that it is being escalated yet nothing happens. I am at a point where I want to cancel this application and I want my money paid back to me immediately. I also have other products with Telkom and am prepared to move this away at cost due to this poor treatment.
