SLA of 5 days

Their SLA on fixing connectivity issues is 5 days! The last time we lost internet access took them 4.5 days to fix. Yesterday I lost connection in the middle of a business VC - 18 hours and counting with no connection so far. As someone who works from home, this is ****ing me. Thankfully MTN are installing fibre in my street, so as soon as they are complete I will be changing.
