Impolite and refuse to resend voucher

Annually Edgars sends a Christmas voucher, mine was sent via sms. My phone broke and therefore I lost the message with the voucher code. However my number is the same. I went into the store and they advised that I contact Edgars club, which I did. But the people at the call center are impolite in the manner in which they spoke to me, they are there to help with a smile, I am in a service department myself and I wouldnt speak to my customers in that manner. The lady said she cant resend and that was that. I spoke to her manager, who then said she will call the nearest store for me. I have been a member for many years now and this is the first time I had an issue like this. If you cant get friendly helpful people who will go out of their way to help, remove them! I pay for my club membership diligently every month so this is unacceptable.
