Shocking Service yet AGAIN!

I had a new device fitted into one of my vehicles with Car Track. Agreement was I would pay R190 pm over 3 months. I was debited R190 on 23 Nov, R417 on 16 Dec, R190 24/12 in ADDITION to my monthly subscription of R215 which was debited in the beginning of November and December. I phoned and spoke to Siphokazi Ndamase, she said she needed to refer this to her supervisor and promised she would call back the same day. Needless to say I do not receive a call and when I called she and the supervisor went home. She also advised that if I was to get a refund I would have to wait 40 days for a refund - WHY????? IT IS YOUR ERROR??? I have since had debits returned by my Bank because CARTRACK ARE HAVING A FIELD DAY WITH DEBITING MY ACCOUNT WITHOUT AUTHORITY!!!!!!!
