Terrible after Sales service from WesBank & Landrover East Rand "Super Group"

Terrible Service! Bought a vehicle from Land Rover East Rand which is a Super Group Dealership and dealt with a guy by the name of Asif Shaik who works for WesBank and is based at the dealership. After much back and forth getting him to take all sorts of sneaky extras he had added into the deal we managed to finalize everything and he sold me a Top-up insurance cover. The Vehicle was subsequently written off and I am yet to receive a letter saying everything has been paid up or a statement showing that I owe Zero after months of battling I reached out to Asif who was very quick to say he only does new sales and finance agreements which to me is unacceptable he should be able to assist in this matter as well as help me cancel the Top-up insurance policy he sold me! My emails are not being responded to and I think this is a poor show of Both Wesbank and Land Rover East Rand!
