Useless Debtors Department!

We hold a business account with Builders Warehouse and have NEVER received such terrible terrible service. The receptionist out right told us "Tumelo told me not to put your call through to him". I mean what a joke! We ordered new account cards as ours are worn out and used. Tumelo Moshoge then does the request for us (8 DAYS LATER after we had to follow up) but in the interim all our cards are suddenly deactivated and our new cards will take 5 working days to be delivered (17 days later) to our chosen branch, AND NOBODY CARED TO LET US KNOW THAT THE CURRENT ONE'S ARE DEACTIVATED AND WHY. Since Friday we have emailed twice, phoned 3 times, all just to ask why they would deactivate the current cards without the new ones being delivered because we use Builders on a daily basis, and the only response thus far is "There's a problem with the courier, it will be delivered in 5 days", and then the phone call where the receptionist so gracefully said Tumelo literally told her not to put the call through. We have put the proposal through to our CEO to leave Builders and open an account at Chamberlains or Leroy Merlin. Places with employees who actually care about customer service and giving their best. What an absolute JOKE!
