cannot be bothered to reply or assist

I informed Indwe risk services on the 18th of last month that my phone had a problem. They immediately sent someone to collect it. And a few days later I received an email saying it would be fixed or replaced under warranty. Since then I haven't heard anything and the frustrating thing is that they cannot be bothered to respond to my mails. I phoned their partners and spoke to Karin Abdulla from Insrap who promised to phone back in 5 minutes. She did not. I called again and she said \sweety don't worry as soon as the supplier brings it I will collect and deliver". Excuse me? When will I receive my cellphone? I have had to go on holiday without it because they could not be bothered to fix it let alone communicate with me. It has been 3 weeks and I have no concrete knowledge of my cel's whereabouts!"""
