Incompetence, failure to communicate and to deliver

My latest experience with dotsure had been very frustrating. I claimed and was told my claim was registered. The lady helping me promised that they will call me back and they never did. I sent the email and it was never acknowledged by the Dotsure office. I called several times and same story, I quote “well call you back” and never did. I sent the message on messenger I’m promised the call back and it never happens. Today I’m told the claim had been registered which is the 4th time I’m hearing this, which means my claim was not registered before. This is my last resort to post here and hoping I can assistance. Dotsure had anyway excelled in everything they did before. I had asked my church members and all my friends to insure with them. I’m just disappointed at this latest incompetence I’m experiencing
