Permanently unavailable to render a service

I have been struggling for almost 8 weeks to obtain any service from MTN to fix my phone.<br> <br> My phone broke on 06/07/2015. I tried contacting the repair centre telephonically but each time I phoned the automated answering system provided the working hours and then dropped the line. Eventually I went to the walk-in repair centre and handed my phone in for repairs on 04/07/2015. I faxed the claim forms to the MTN insurance on the 06/07/2015. I queried the repair process on 15/07/2015 by emailing the repair centre. I only received a response when I emailed again on the 21/07/2015.<br> <br> On the 21/07/2015 I was provided with a quotation to repair the device. The email also indicated that I should contact the insurance on ***. I have phoned the number repeatedly since the 21/07/2015 but the automated answering system takes me through a process, indicating \temporary technical difficulty"and then the lines drops.<br> <br> I have contacted MTN via email on 15/23/24/27/28 July and have been phoning the call centre line relentlessly"
