Pathetic Call Centre

Pathetic cusfomer service from the contact centre.I have been trying to get Builders Warehouse to reissue by Birthday voucher,however it is as if I am asking for water out of a stone.I called on Thursday 23rd of Oct,I was tild by the agent he will send the request to his manager.A few hours later,another call from a different agent to query the matter and like a scripted call, was advised exactly what the first agent mentioned i.e.thwy will send the request to the manager.I called again on Friday(24th Oct) and was told that the request was sent to head office(they are Head Office,by the way).I called on the 27th at 9:10am, again and asked to speak to a manager,I was then transferred to Chante.Chante promised to look into the matter and give me a call by 2pm latest as she needed to check with the agent.I dont understand why it would take 5 hours to check with the agent.2pm came and went no phonecall.I called again on the 28th of Oct,Chante was in a meeting and a messagw was left to call be back at 11 after her meeting,11am came and went,no phonecall.I called again at around 2pm,I was told again that all supervisors and managers are in a mwetinf.To date I do not have my birthday voucher,and I am yet ro recieve a phonecall from Chante.No one gives a damn about customer service.Dont offer loyalty voucher if you cant fulfill them through customer service.I eventually got a call from Muneer to notify me that the request is at Head office,they will escalate the matter(6 days later).An escalation should have taken during the second call and not the seventh.This is delaying my project and BW has no care in the world.Managers and supervisors dealing this matter have a laid back attitude with no sense of customer service Agents have to answer for the failure of their managers to act whilst the managers and supervisors hide beind the agents!Pathetic!
