Sons tablet not repaired for three months

Repair Note: *** I bought my son a Hisense Sero 7 tablet for Christmas. After two days of normal use I notices a crack on the screen over the camera area. As we were on holiday at a resort I only managed to take the tablet in to Makro on 5 January 2015. I took them two weeks to assess the tablet.<br> I was told that I will have to pay for the screen repairs as it is not covered under warranty. I paid the amount charged for the repair on 2 February 2015. I was told that the tablet should be fixed within a week as my son really wanted his tablet back.<br> I phoned after a week. I was told that I did not pay the amount yet. After a quick check it was found that I did pay the amount but that the paperwork confirming this were not send to Hisense so the repair did not take place. I was told that the repair should be finalised after two weeks.<br> I phone again after two weeks. I was told that Hisense is waiting for the part. I then phone every week from there and was told the same thing.<br> On Sonday 22 March 2015 I went and saw the Manager at repairs. He said I must give him three workings days and that he will the resolve the issue. Have not received a phone call from him yet.
