Parcel returned to Telkom due to sales agent not putting my flat number. Parcel still not returned after many calls no one can assist

I did a telephonic order with Nompumelelo Simelani for a Z Fold 4. It was approved and i received my tracking number. Once my parcel arrived with the courier the refused to give me my parcel as they said that the agent did not include my flat number. I called Telkom and asked them to rectify the matter which didnt happen. Parcel was sent back to Telkom i called everyday and was over promised only to find out that i couldnt get my parcel back. Week later Nompumelelo called me to rectify the matter and till now i dont know whether ill ever recieved the phone i ordered. Im dissappointed and shocked at the service ive received
