Totally disgusting service

On 18 November 2017 I booked in my Huawei P8 lite for repairs. After about 3 weeks of no feedback (After I received a sms saying a technician/agent would be in contact with me within 48 hours on 21 November 2017) I decided to give Glo cell a call and just get some update which the agent then said she would give me a call back. Within 2 days of that call I called back and then was promised another phone call back from a different agent who also just simply never called back. On the 7 December 2017 I received a sms saying my quote was rejected (which I never received) and that the device will be sent back to collection point. We are now almost in the new year and I still wait for my phone. Glo cell simply do not know about client service and are FULL of empty promises. It cannot take 20 days from date of sms saying phone will be returned and still the phone is not in Cape Town after being told yesterday it would be at the store today. I have a manager involved and quite simply I see that if management is so slack I cannot really expect the agents to be on the ball. Glo cell is a terrible service provider and simply do not call their clients back. No service what so ever.
