I'm so disappointed in cartrack😭

I'm so disappointed in cartrack! It's been weeks since they promised to fix their mess but I always get empty promises. They were supposed to uninstall the tracker in my old car that I sold and install it in my new car but instead they installed a new tracker and now I'm paying for 2 cartrackers even though the other car is sold. Gomolemo, the lady responsible for all this mess called me last week and promised me that her manager was going to cancel the contract for the old car last week Friday free of charge but up to now the tracker is still active. I have been calling them non stop but I'm not getting any help. I'm exhausted. I'm helpless. Please do the right thing!
