Why?

Merchant ref ***. Was promised technician would come repair my faulty merchant machine this morning. No technician has arrived. Was told the technician is stuck in traffic so that's why he can't make it today. Team leaders have all gone home. Month end Friday now my customers are inconvenienced. Why have a call centre where nobody can assist?. This has happened all too often. Merchant number ***. Please prepare the documents for me to cancel this service with you guys asap. Tired of struggling to get service. Tired of paying a fortune in bank fees for zero in return.
