Bad service from Telkom

We moved house on the 8th of January 2018. Early December 2017 we went to the Tygervalley branch of Telkom to notify them of the change of address as well as the new contract needed. That were all done in a professional manner but every thing just stopped there. Since then, after numerous calls to different departments, they are still busy locating the address. That house has been standing there for more than 30 years and have all the telephone lines installed. Except for the fact that we are almost in March, how can it be possible that an address can disappear from their system?
