Tracker customer service non existent

Impossible to cancel a subscription. Spoke to Gugu on Tues at 2pm she said she would call back as the cancellation dept was very busy, STILL waiting. (second time they have promised to call back now). Left a message on-line needless to say I'm still waiting..... What you people don't realise is even though I have sold my car, when it comes to replacing it, due to the poor service received now, I will NOT be using Tracker again. Look at the bigger picture!!
