Frustration and poorest service!!

Again such bad experience o n my insurance through cell c!! Previously i battled for 6 months to get my deviced replaced after call upon call, drop calls and endless waiting after 100's of messages. I am now again going through the same frustrations!! Handed in my claim the 14th of September, followed up the 25th. Answer i got, claim with manager for sign off, followed up in between and again today!! Guess what!! Claim still with manager! 3 weeks later??? Getting no joy! Phoned 3 times today held on for 10 minutes and cutt off, been put through 2nd time and cutt off! 3rd time lucky, spoke to agent, held on for about 12 minutes and dropped the call on me!! Frustration and pathetic service! Manager never available!! I pay insurance and my monthly contractual fee and get this service?? I refuse to wait another 6 months for my phone!! Never experienced such incompetence in my entire live!
