Bad client service at Liberty

I joined their latest tax free initiative STASH. Looked like a wonderful tool to start saving the odd cent or two. But it has many bugs, most notably was the one where they debited my account with 1000s of rands which is yet to be sorted out after 4 months of trying! Attempted to contact them with very little response. In short the like ALL Liberty products the product is a good idea but the customer service is atrocious! I have had a better time crossing the beitbridge border post into Zimbabwe than dealing with liberty client service.
