Who will pay my R5500 data bill???

Our Telkom underground cable was damamged on the 6th March 2015. I returned from a business trip on the 8th March to find that my ADSL line as well as my telephone line was not working. I logged the fault (269CTK080315) with 10210 and informed the call center that this was an URGENT matter as i need the lines for work. On the 15th March the fault was closed on Telkoms side without it being fixed. I called the call center again and said that the fault was NOT fixed and received a NEW fault number (129CTK150315). This fault was finally fixed on the 30th March. I however could not let my business stand still due to Telkoms lack a service and had to use my 3G connection. Now i have a bill for R5519.26 to pay and i am still being changes for the line rental for March from Telkom. WHO IS GOING TO PAY THE R5519.26???? I have contact Details for a Susan Forster but this mail address given to me is incorrect...
