Worst service by far

I called the shop on more than one occasion to inquire about an expiry date on an item i had on a buy back, as I was out of Gauteng, the first call a lady picked up and just told me they were in a meeting and then she dropped the phone, 2nd call I was told that they would not provide me with such information, if I need anything from the shop I am supposed to go to the shop, the third person then just told me to stop calling them as they had a line of customers waiting in the shop and that I was wasting their time and on all occasions the phone would be dropped when asking for the respondents name. I must say that this is by far the worst service I have received from a cash converters shop.
