Error when redeeming points for a gift card

[Sparkaction]

I tried to redeem points for a GC.  The Telus site asked me if they could call or txt my landline so I selected call.  When I receive the call, the system says a TTS error has been detected or something similar about a TTS error.  How to I resolve this issue?

Hello. Did you try the text option?
