3 months and still NO Landline

A request was made on 15 May 2019 to change ownership of a landline, from my passed father's name to mine. The phone number had to kept the same. The initial request was done via the Telkom Call Center. After 3 weeks of no feedback an update from my local store was requested. Turns out the new account was again om my deceased father's name. After 3 months of continuous visits to the Telkom Store (and 3 incorrect numbers further) the number is still incorrect. I have given up!!!
