They never arrived friday either, had a rather less than polite conversation with their HQ in Bangkok.
Informed them that i would be reducing their next bill for non-service and around 100 bahts worth of phone calls to their poxy company. They appeared ok about it which really narked me
The technicians have phoned and are arriving at any moment to install the new box. I can assure their company that they wont be leaving until i am fully satisfied that all is well. If not then i will be deflating their vehicle tyres, hiding the ignition keys and of course pulling out the Armalite from under the bed.
