telkom cannot resolve a issue with a stuck order

requested my line to be moved 7 weeks ago , telkom reference number CBS303968 i phone telkom at least 5 times a week ,FIRST OF ALL I GET TOLD MY CELL NUMBER IS INCORRECT , now when you phone telkom they confirm your cell number , id number name , surname , address , i get told the order has not been generated , NOW the order is stuck , the person who is responsible for this order is on leave , i have spoken to Nathi ********** 485 who promised to come back to me , i have left numerous voice mails for him to contact me he does not , the person responsible for the order name is Arthur Sparks , he is missing in action i then spoke to his manager today he promised to phone me back with a resolution his name is Ameer ********** 526.he tells me there is a issue with this order system and it has been down for the past 3 months , he cannot over ride the system and i must just shut up and wait , what telkom does not fathom is my business is run from home we use internet so far this has cost me 400gigs of data at mtn pricing of 160 rand a gig , huge money R64000.00 TO BE EXACT . if telkom management cannot resolve this issue and bring the responsible person before a hearing then i want to sue the person responsible for this in his personal capacity for the losses i have incurred due to him not doing what he has been employed to do ,
