System issues become clients responsibility

I've been with telkom for almost a decade now and I expect a level of friction however everytime there is something new that blows up.

I took out a contract with a device that was fault and the branch didn't keep me informed nor showed any interest in making sure my contract was cancelled efficiently. That finally happened yet no one tells me what will happen with the outstanding amount.

That aside they have supply issues with samsung device and watch I want - which is why I ordered online - gave my address for delivery and all seemed well. Today the courier arrived and said they have a completely different address for me - a house a street or two away from me and they cannot give me my device. Annoyed I called telkom and it turned out when the sale was made the agent just placed any address under my name because their system cannot find my address - their system issue is now my issue. I need to go collect the device from the courier depot 30km away from me, I need to visit the telkom store to change the incorrect address (violating someone else right in the POPI act) and further to that I need a special permission slip to collect the device. All in all not a smooth process
