My phone is still in for repairs.

My cellphone was due for upgrade and i decided to take the LG G4 as the sales per in store assured me LG had produced a number of good phone since the last LG i owned and promised never to get again. Just after a month of owning this brand new phone, it began to freeze, beep continuously, display a static screen and rebooot itself. I booked the phone in for repairs and was told that it would take no longer than 21 days to return. The phone was booked in on the 16th of March. It is now the 10th of April, and i still have no phone nor any indication of it returning anytime soon. It is 2016 and the average person cannot last without a phone for very long. Leaving a customer phone-less for such a lengthy period of time is unacceptable in this day and age. It all boils down to poor service delivery. I regret my decision to port to Cell C and to choose this LG handset. The phone was never dropped nor did it receive any liquid damage and one of the first few apps downloaded off Google Play was an Antivirus. I still do not understand why i was not issued a new handset, as the problems on the phone were due to manufacturing errors. Extremely dissatisfied !!!!!
