POOR CELLPHONE CLAIM SERVICE

In April/ may this year I was offered cellphone cover by the unlimited. It sounded great. I recently laid a claim on the 28th July. It is now the 17th Aug and my cellphone still hasn't been picked up. Everytime I call (aaaand yes I, as the client, am constantly calling them to check up) I get told by the administrators that the claim is approved and the unlimited is responsible for calling new with further instructions. I am currently without a smart phone therefore I can't bank or actually function at full capacity. I am frustrated and tired and want to cancel this stupid cover with IMMEDIATE effect. This is some of the worst service ever.
