Most pathetic service ever experienced

Call centre is pathetic, they do not know what is going on in the company. They promise to attend to your issue but the never do. They promise to call you back with updates but this has not happned with the last several calls I had to make. I have sent in my damaged phone 3 months ago, to my knowledge they just threw it in storage. I don't know what to do more. I have sent complaint emails with only more promises to attend to my issue. I would not recommend this insurance scheme to anyone.
