Mall@55 spec savers poor service and lack of communication

i find the service that i have received from Spec Savers at Mall @ 55 in Centurion to be appalling. i have made 3 calls to them to follow up on when i will be receiving my spectacles and i get the same excuse, that they haven't arrived or they will call me back but they never do and i have to call them. there is no communication sent to me just to manage my expectation and they are just silent. but it was nice when they claimed r5000 from me which they have been paid but i do not have the product to date.
