Why bother having customer care agents

I ordered goodies online on Wednesday the 21st OCT. It would not accept my voucher so I sent a mail to customer care. Got a response saying someone will get back to me in 24 hours. Well, Thursday I called in to design quarter because I know boardmans online service is revolting. A lady took all my details, she could not help me but someone else will give me a call back on Thursday afternoon. I explained the goodies I wanted was on sale and was promised I would get feedback. Friday I call again as true to Boardmans style no one had got back to me. this time it will be escalated and someone will give me a call. By Friday evening still no call. I was in CT until Monday. Tuesday I get an e-mail back. 6 days after the 24 hours promised Sorry but no vouchers can be used online. If only someone had told me that I would have come in and bought my goodies while they were on sale. I asked for a manager to call me back. I suppose this will take another week! DISGUSTING SERVICE boardmans. Sure other reputable companies will love my business.
