Musica - Tygervalley - bad experience

We bought a Dual charging cable from Musica. the 1st time it broke the Manageress at Musica Tygervalley helped us to exchange it no problems at all. She even went to the trouble to find my slip on the system, because I forgot my slip. Yesterday when I went there the staff there was not very helpful at all. They 1st made we wait for a very long time, with no one coming to help me although I did tell them I need some help with and exchange. Then when someone came to help me the guy told me that there is only a 7 day warranty on the item and he did not want to help me any further. We were in lock down for 4 months and that is how he helps me. Do they want us to buy again from them? I will definitely think twice before I buy anything from them again that is for sure.
