landline out of order

Reported my business landline out of order on August 25, 2015 refno 385CRZ250815. After a week I phoned again, this querie was escalated, but still nothing happens. No service - no maintenance. Telkom you are breeching our contract. For more then 2 weeks we do not have any service. When are you going to fix this line. Further I request a refund on my subscription for the period my line will be out of order.. Further my home landline has been out of order since July 2, 2015 When is this going to be fix? Escalated - no progress
