Protea Glen Boulevard PnP bad service

On the 24th of February I bought 2 adapters and when I tried to use them only to find out that they are faulty. I then wen to the store in the 2nd March and Thembisile and the manager Mr Makau told me that they can't assist me because I lost the plastic these adapters were in so they will ask the supplier what to do so they will call me coz the supplier normally comes on Tuesday. They did not call me on Tuesday and I then went back on Wednesday and Mr Makau said he will try and get hold of the supplier as his not answering his phone. I understood and to my surprise again I was kept on the loop on this and they have taken back these adapters. I then on Friday call the customer care line where I was connected to Mr Makau who apologized about not calling and promised to call me in 10 minutes and that also never happened hence I'm using now this platform. How long does it take to get such a matter resolved, there is clearly no professionalism in this store, they don't care about the client and resolving complaints. How long does it take to resolve complaints? I need my money back as they don't have other brand of adapters and I cannot take faulty things and even the manager did test it and he saw that they were faulty.
