Terrible customer service

In summary. I recieved a voucher on 9 Feb to which they said an sms will be received with the voucher. Never received the sms. Took the invoice in store, where the chashier had no idea what to do and had to ask them to get someone who can have a look. They are easy to just not try. They logged it and called where they said it will be received within 48 hours. This did not happen, then the Friday Bonile said another 24 hours. And again nothing the Monday when i waited 24 hours, excluding the weekend. When I asked Michelle to transfer me to a manager because everyone is making promises with no delivery she also ignored this and transfered me to the consultant again who insisted he wants to explain what happened and another email recieved from him to say it will take another 24 hours. I mean really, when i got irate, all of sudden he can arrange for it to be done within an hour because i was upset clearly making this 24 hour delays just ridiculous as he could then have handled this enquiry within an hour on Friday as well. I had to ask numerous times to speak to a manager but he wanted to get his point across as to the why it was delayed. He does not understand the why does not matter when at this point the trust as a client has already been lost. So lets see if he can ask his manager to call as he said. Clicks customer service is clearly not "feel good" service as their brand promotes. They would rather argue the "why they couldn't" than stepup and handle the enquiry which apparently can be done sooner than 24 hours!!!
