Poor Services and Bad attitude

On the 4th of October i went to Ok store to report my fridge that is not working,they promised to process my claim and send ppl from Defy to fix my fridge asap,but up till today nothing happened i kept calling them no help every time i call they ask for my details and promise to get back to me thy never did,a lady by the name of chanel kept on telling me she cant get hold of the head office for 2 consecutive when ever i call her that's the answer she gives me i called the complaints department spoke to Charmain she decide to shout at me when i explain my matter,i called the head office i jhb they gave me an extension for their Manager i spoke to her she insisted on forwarding my call to the insurance department that i have been dealing with already instead of hearing me out when i was trying to explain my problem she just transferred my call and i again got a promise that they will call me back but they neva did till today.. i am very upset and my groccer is spoiled i dnt know i must wait for how long i dnt know what is their turner round time no services at all. i am so upset.with these people from Ok....
