I had 3 accounts with Slingshot/Callplus.
I continue to use Callplus services at my offices.
I had slingshot at home but cancelled that.
I had slingshot at my beachouse but cancelled that in September 2016.
Slingshot have continued to charge me since September 2016. Unfortunately my wife only just noticed this, this month. I called and whilst the caller acknowledged that the service was not used, will not reimburse me.
I tried to speak to someone more senior even suggesting that I move my internet back to slingshot and be credited with this amount but can't really get past the call centre staff.
