Pick N pay montana

I bought a hisense washing machine at PNP Montana last year n that's where I bought most of my appliances and their service has been good I have been assisted by a guy called Itumeleng... So three weeks back I went to report that my washing machine has a problem because it's still under guarantee, Itu helped me and said he will call the hisense people on Monday 27th May because I was there on a Saturday 25th... On the 28 and the 30th I called Pnp Montana to find out how long do I still have to wait for the technician to come and checkout the machine and that since I went there no one has been updating me on what's happening I have taken it on my to do the follow up... So the manager called Itumelengover the phone n he told me that He is not sure how long its still gonna take for a technician to come as hisense is not the same as defy they send these people emails and they still haven't responded as he sent the form on Tuesday the 28th of May...i am starting a 3rd week now still haven't heard anything from pnp or hisense about the machine.... It's so nice when u r sold a product it's so difficult to maintain the service now I am so disappointed with the service it's winter now I am arthritic yet I get this kind of a problem.
