I took out a tracker with them last month, consultant that helped me, didn't inform me about pro-rata that was going to deduct on the 25th June, and if she had offered me the pro-rata I could have refused cause I am unemployed at the moment so I can't afford it. Now I have been requesting them for numerous occasions to fix this mistake, been writing emails to their customer service/accounts dpt/consultant that serviced me, calling and calling asking them to call me back nobody is coming to my rescue, no response at all. I just wanted them to fix the mistake that was made by the system or the consultant, I even asked them to listen to the recordings, nothing is done. This is bad service
