Cell C Upgrade misery

<p> </p> <p>I upgraded to a Sony Xperia M5 by calling Cell C on the 8 August and received the upgrade via Ram Couriers on the 10 August 2016. I Logged fault with the phone on 15 August and Ram Couriers picked up the faulty phone on the 16 August 2016. Heard nothing after that, so called on the 20 August. They told me the system shows it was picked up, it will be with the repair department but nothing else is on the system. I called back again on the 22 August, they told me that it was not booked with a technician yet and nothing else is on the system, but they will go over and find out when it will be looked at and call me back later that day. No one called me back but I received an SMS on the 24 August saying my phone had been looked at and approved as an OBF (Out of box failure) and I need to order a replacement. I then ordered the replacement on the 25 August, followed up on the 26 August and they told me I should receive it Monday so I follow up on Monday 29 August 2016, only to be told they are out of stock, I need to order a different phone for my upgrade, they do not know when they will be getting stock in. I asked if they could not get one from a store and they said no, as stores run separately. I asked to speak to the manager and the consultant told me the manager will tell me the same thing, but I insisted and he put me on hold to go to call the manager. He then returned and told me the manager (Maina) will call me from her desk. No one called me back.</p> <p> </p> <p> </p>
