Shocking Service.

I took my laptop in for repairs a week ago. They wanted to charge me almost R700 for a 24 hour assessment - not to repair it, only to assess, no guarantees about being able to fix it. I use my laptop for my work so no laptop means no income. My laptop has a 2 year fetch and repair warranty and was super expensive so to avoid unnecessary costs I decided not to to this hellishly expensive assessment. They assured me the normal warranty assessment would take 2-3 working days, not longer - definitely. After 3 days I called them and they said my laptop had gone in for assessment and they would advise by the end of the day. No one called me at the end of the day. I called yesterday and the issue was escalated and again I was told I would be contacted about it by the end of yesterday. Nothing. I am still waiting - now 5 days later. I am unable to work or earn a living during this wait - the laptop has not even gone in for repairs - this is just for the assessment. I am totally annoyed and frustrated by this shocking level of service. If they could not do the job in the time they specified, they should not have taken it on - I could have gone somewhere else.
