Lawyers handovers on up to date accounts!

We had given a clear instruction with a full confirmed paper trail to Wesbank to move our debit order from the 15th to the 23rd of each month and we were told it cant be done a second time and we can do a monthly EFT. We have paid religiously ever since and for the past 3 days we started getting harassing calls from Wesbank's collection solutions threatening us with action even though the account is fully up to date!! Having said that we then got told we need to pay a lawyers fee now as well. We have NEVER been in arrears and even our statement proofs it! I urge other consumers to be extremely careful when doing business with Wesbank and NOT to get swept away with the excitement of their new car purchase. A few month later it will become your biggest nightmare!!
