Poor communication and complaint resolution

Zero communications between different departments within the company. Bought a tracking device with my new car. Ended up being charged R2850 again for the device even though i bought the unit already. Clueless people from their account dept will call 5 to 10 times a week for the same issue even after i was told that it was a mistake on their side. Eventually they ended up debiting my account with a debit order. Extremely slow and inefficient complaint resolution, do not recommend.
