pathetic service

I am a regular customer of Zando and make sure that all my payments are up to date. for the past 2 orders (in less than a week apart) they have failed to deliver good service. I get emails to make payment even after i have sent through proof of PAYMENTS, emails and made calls to them. i rarely get any tangible feedback from them pertaining to both the orders i have place and paid for via EFT. No one even bothers to apologies for the inconvenience they have caused. I am extremely unhappy about this and I would like to air my complaint about the very poor service that I received. I am unhappy about the quality of the turnaround time of confirming my payment and the time it took for someone to get back to me. What made matters worse was that these particular items were meant to be a present for my sister for her birthday tomorrow (3rd June). The service I received from Zando was nothing like what I know Zando's brand offers to their customers, especially considering that I made a purchase using a voucher and paying the balance via EFT that should have immediately reflected on their system that payment has been made for that order. I am truly upset an angry about this.
