Pathetic service

I handed my Blackberry Q5 in to have the battery replaced. I left my phone at the branch as they had to order a battery. Michael said he would phone me but when he didn't phone me I phoned him on the next Wednesday ( I handed in on the 13th of June) he then said that there is a software problem that they didn't know how to fix. They then sent it to the \experts"I spoke to Michael various times and he told me the so called experts are battling with the phone. I spoke to him again last week Tuesday and he said that the experts found the problem and I would get my phone on Friday the 31st July. I phone on Saturday and spoke to another guy who said he thinks his boss went to fetch my phone. I phoned this morning and spoke to Michael who told me the phone is still not fixed. """
