Took nearly a month to deliver order that should have taken 3 - 5 working days

Took close to a month to "deliver" stock, eventually cancelled order, as it clearly was not going to be delivered. (SLA given was 3 - 5 working days) Got sent from pillar to post (spoke to 5 different agents) over a period 3 weeks to ascertain where delivery, each agent had a different story. Got put on hold for more than half an hour, thereafter call was hung up as agent went home. Have to follow up on query, as previous agents would mark your query as RESOLVED, when no feedback or resolution has taken place.
