Delayed responses and bad service from Bonitas

A few weeks ago on the 15 April 2015 i was referred to Len-med Hospital by My general practitioner due to pains on the left side of my chest (needed urgent attention) when I arrived at the hospital they informed me that I would need to pay cash and claim from my medical aid as thier call center was closed. I paid the amount and sent the invoice to Bonitas on the 21 April 2015. I called them twice within that week and didn't receive a valid or helpful answer. I then enquired again about my claim the following week spending again over R30 airtime speaking to a consultant who then assured me that she would send through my claim. After endless emails and Bonitas just sending me a new ref number ( I have 6 reference numbers for this query and no response as to whether the claim will be paid) I got fed up yesterday and sent a request to cancel my account and I explained why. I received an email today saying my termination is being handled. Im so disappointed i really enjoyed being on Bonitas and had no complaints up til now but its clear that they are very willing to terminate accounts instead of attending to customer queries.
