The death of a 10-year relationship

I've been a long-standing customer of Munlin Travel for over 10 years...until now. Sadly, the death of an excellent travel agent - Lyn - has all but highlighted how inept the rest of the Munlin team is. As someone who spends more than R500 000 per annum on travel - none of which is high-priced Business Class - and travels no less than twice monthly (on average), I'm not what I'd assume to be a travel novice, nor an overly easy customer to please. I want what I want...and have always been VERY clear about that, yet Munlin can no longer seem to deliver on my expectations. Over-billings. Failure to notify of visa requirements. Lack of product knowledge. Incomepetencies in issuing correct travel vouchers. Delays in responding to requests. An ineffective "emergency number" (3 days wait for a reply). These are but some of the frustrations I've had to endure...but will no longer endure from Munlin Travel.
