Poor service

I have been phoning them since 29 Feb 2016 for my receipt which I didn't get from KC branch for my Twisp device, they suppose to phone me when its ready for collection,but I'm still waiting.I then contacted head office the following week and useless as well, cos they said they cant get hold of the kiosk, how is that even possible,then TD said he'll send out the Area Manager who also probably got lost nothing came of that and then they refuse to returns my calls. I needed to return the device as it has a 10 day cooling period,but I cant because I saw first hand how another customer at the kiosk was arguing with the salesperson, cos the one he did the sale with said the same to him and has been relocated to a new branch and they cant get hold of him to confirm, I AM VeRY FRUSTRATED and very upset with them becos no one follows up , and now my device is giving me hassles, and TD wants ME to BRING it to Head office, why must I drive around what kind of service is this, why must I drive from Kiosk to Kiosk to get AFTER SALES SERVICE. I'm actually loosing my patience with TWISP, they are just USELESS. the only nice KIOSK is N1 City...... nice staff and wonderful service
