No assistance, dissapointing after care

DNA Monster headset<br> I purchased the headset from Musica Gateway. I was assisted very eagerly by the consultant when i purchased the headset. I went back to the store to have the headset repaired(the cushion was beginning to detach itself from the headset), i was told that i can't be assisted as they don't stock the brand anymore. I asked if there is a number for the supplier , they said they don't have the number for the supplier. Very unhelpful. The item was expensive( Between R2500 to R3000), i expected better service and the reception than i received. I then went to the Pavilion branch for help and the sales consultant told me he cannot help me. Few weeks later i went to purchase a Vinyl player and was assisted by a manager who informed me he will assist me to get the details of the suppliers that they use to communicate with regarding the DNA headsets. He took down my details but did not get back to me. I went back a week later to enquire, the manager told me he forgot, he said he will definitely get the details and contact me and a week later I am still waiting. I humbly appeal to musica to please get me the details so I can get my headset fixed.
