Mtn Business based in Cradock -Complaint

Greetings, I would like to lay a complaint for a the Mtn business in Cradock. Last year October 2018 I sent in my Laptop at the Mtn store for repairs, the screen did not want to switch on it only allows me to put in my password and than it goes blank. The consultant name Hendry (nickname is faba) He helped us at the counter, took the laptop and assured me that the laptop would be fixed within 2months . He did tell us it takes 4months maximum for customers to wait for their electronics to be repaired which I did wait 4 months for. I went to the shop for any feedback about my laptop and Hendry said that it's on its way. I went back to the store everyday for 3 days for my laptop and still I never received it. He lastly told me at my last visit that he got a email to say that the laptop is on its way. Ok fine I came back the 4th day. I received my laptop and all Hendry said that I should enter my password than all should be fine. I returned home very excited to switch my laptop on and I noticed I didn't receive any sticker to say the laptop was sent for repairs neither did I receive any paper regarding my laptop. Hentry only gave me my laptop in a hurry for me to just leave the store. I switched my laptop on and once again it made the same thing. I put in my password and blank was the screen again. My laptop was never sent for repairs for 4 months and I was never contacted as to why. I'm sitting at home now with a laptop that is not working at all and I still have to pay for my laptop. As I did buy it on contract. I'm very disappointed in this and I refuse to pay for something that is no longer in working condition. I would like to receive urgent feedback on this. My contact number is ********** 890.
