Despicable service from The Foschini Group/@Home

I logged a complaint on the FB page re an incorrect account balance on my mother's account. I then sent and email to their HO in Cape Town. They requested a signed approval letter to act on behalf of mother (she isn't email or internet savvy) which was provide. They have not made any attempts to make contact with me or my mother and now ignore my messages on the FB page as well as my emails. My last email contact contact was with Tiffany Barron, Administrator-Customer Services, and she has not bothered to respond to my complaints. Their comment on their FB page is that they do not subscribe to Hello Peter. Shocking Service!!! My next complaint with be to the CEO of the Foschini Group Anthony Thunstrom
