Disgusted at the service

Very dissatisfied at the service at Iwyze gap cover. I submitted a claim 2 weeks ago and have heard nothing from them. I called in yesterday, only to be told that the claim was captured incorrectly and that I need to submit more information. I do so this morning, have placed 2 call back requests over the last week and have heard nothing. I am now holding on the line for 40 mins to be assisted,i am being told for the last 30 mins that my call is next in line. I am utterly shocked at this level of service, not something I expect from old mutual. I would rather move my cover to a more competent company. They are really not interested in their clients
