telkom fibre not working and not installed for 5 weeks

i recently received a call from telkom approximately a 2 months ago to upgrade my adsl line to fibre. my ADSL Line will be discontinued as of 31 march 2023. i agreed to upgrade to fibre. telkom arranged to install my fibre . however when the installer arrived , the fibre router was not delivered . the D-LINK ROUTER was delivered 4 days later prior to fibre installation. its been now 5 - 6 weeks and my fibre router is still not installed . i have contacted telkom technical support,sales support, fault department. spoke to over 20 consultants in different departments. nobody seems to know who is responsible for the correct installation. i have a telkom reference number: ***3. still no help from telkom and they billed me for both adsl and fibre service that is not working. extremely bad service and unhappy customer.
