Horrific service

I currently have a contract with Telkom, the ADSL line so 3 weeks ago i was contacted by a Telkom technician telling me that he needs to come to my house and migrate my package to Fibre, so the technician came thru and positioned our fibre in a new place then where the ADSL line was, now the problem is with this whole new fibre we have been having endless problems the internet ia super sloe and not covering all the house, when i called, Telkom and explained my quey im being sent from Pillar service at Telkom is horrible iam being told that the technician positioned it in better now i have to dig in my pocket and buy an additional router and extender cable, yet i am paying for a service that im not getting and also do not have an additional money. I really feel like Telkom is treating me like a 3rd claes citizen and also being a woman they are taking advantage of me, all i want from Telkom is for them to come back and sort out the mess thay have created my ADSL line was working perfectly fine until this horrible Fibre deal came along.. Another issue is that when i took the contract i specifically told the consultant that my pay date is the 15th of each month all subscriptions must go on the 15th to my suprise im debited on thr last day of the hr month which is a huge inconvenience on my side. At the moment i would never refer anyone close to me and Word of mouth is a very powerful marketing tool. I need assistance my family is angry of this new fibre package which has came with alot of issues..
