Avoid at all costs!

PartServe have had my laptop for 2.5 weeks. They are STILL 'waiting for a part' - it's a simple hard drive! Last week I was told they'd made an alternative arrangement and would no longer be waiting for an ETA to get the part from overseas (yes - it hadn't even been shipped yet!) I was promised that it would take 2 days to get from JHB to CT. Called this morning and it still hasn't arrived in CT. They are now telling me the part will arrive on Friday. That will be THREE WEEKS after dropping my laptop off and more than 10 working days from accepting their quote and making payment in full. I go overseas on Saturday as I've been telling them on my daily follow up calls... PATHETIC lack of service and no-one will put me through to management, there's just no solution. After being on hold for 17 minutes again I'm now waiting for someone to call me back with a plan. I have very little faith I'll receive a call as no-one bothered to let me know that the part hadn't arrived and that I wouldn't be getting my laptop back on Thursday as promised on Friday last week. I don't even know what to say.
