Poor Service

I took my JVC tv for repairs to this store, as it is still under guarantee, on the 5 May 2015. I was informed that repairs takes plus or minus 14 working days. When I phoned them last week I was rudely told that it takes 14 working days. So I called the store on 25 May, I was put through the manager who told me he will enquire and call me back. And he did not. So I called him the next day, 26th, and told him that it was now more than 16 working days and I needed my tv. He confirmed that it only takes 14 working days. And that he was short staffed because of the taxi strike. I told him the strike was only for that day, what about the other days before that. He said he will phoned the supplier and come back to me. He called and informed me that the tv was going to be delivered to him that same day, they will test it and they will SMS or call me the next day, the 27th. I didn't get any SMS or call. I called them today. Still no tv, I went to the store, and was told I will get my tv today. I went back to the store before they could close. Still no tv. If the tv cannot be repaired they were supp. To replace or whatever. 18 working days , no Saturdays. No tv. My kids disappoint
