Poor client service

I just want to express disgust at the level of service that I am getting from RAP. These guys have had my handset for more than 2 weeks and they had promised that I would receive a replacement one yesterday. I left someone at my house specifically for this and instead someone came to collect instead of deliver due to what was claimed as an error. I spoke to Karin Abdulla about this and she was oblivious of this incident and instead she offered me an excuse that she could not expand on. I told Karin that I need my device by 10 am today but she has not been able to arrange this, I spoke to her in the morning and she promised that the courier guys would be in touch with me shortly and its 2 pm now and no one has called to give me an explanation of what is happening. I fed up of making follows and no one doing nothing about it, its a worst of my time and money.
