Useless website

3 weeks ago, I unintentionally deleted my overall cellphone cover, when I was trying to take out just one phone. A day later, when I saw my mistake, I tried hopelessly to reinstate the cover online as I have restricted phone usage. I then requested the call back service on their website as I could not add the cover myself. 3 weeks later and I'm still waiting for the phone call. Mind you, every week since the initial call back request, I have been on the website trying to get assistance. I'm at my wits end now and thinking of cancelling my entire insurance cover with them. Why implement a feature on their website when they can't provide the service.
