Extremely dissatisfied and disappointed with Cellc

I have had the most unprofessional experience with Cellc for the past 2 months. I have been using the service provider for over 10 years and when I lost my phone in May this year my insurance provider requested for the last usage date of the device from Cellc and on the cellc system it shows the last usage date of February and my insurance declined my claim.

How can a device that was l used for over a year up until May show the last usage date of February!. What frustrates me the most is that I have been sending multiple emails and calling their customer service line with no feedback. I am extremely dissatisfied and disappointed at Cellc not only because I have been a loyal customer to them for over 10 years but because it is a service provider that I have been recommending to everyone.

They do not treat their customer queries with any sense of emergency nor do they take their precious time to try and investigate why such an issue came about.

I do not have a phone today because of Cellc and they did not even bother to look into the issue or attend to my query. Their service is extremely poor and they do not care about their customers at all!
