Alexander/momentum has not resolved my claim in over a month when they have all the information they need

The worst experience I have ever encountered as it's been a month with my claim not resolved. Tumelo Mabidikama was assigned to be my claim consultant and has refused to do his job as he doesn't answer emails or return calls. After having submitted ALL the required information within a week of the claim, over a month later Tammy, the claims team leader still is telling me that more information is required. No one is doing their job as I have to repeadly email the same info and still be the one, as the client, to chase after Momentum's employees in order to get an update or for just someone to do their job! None of them are ever available telephonically each time I call and I can't even reach customer service personnel.
