Bradlows is the worst when it comes to customer service

Very poor customer service. I placed an order online for an office chair on the 8th of July and paid R1349.95 (R999.95 + R350 for shipping and handling). I sent an email on the 16th asking when I could expect delivery. I received acknowledgement of receipt of my email but nothing further. I sent an email again on the 17th of July and received no response from them. I called their call centre on the 20th of July and was told that someone would call me within 24 hours. I received no call from them. I called the call centre again on the 22nd of July and was told that my query would be escalated and that someone would contact me within 24 hours. Still no call from them 24 hours later. On both occasions when calling the call centre I had to hold on for more than 20 minutes before eventually speaking to someone. On the 28th of July I received an email from them asking whether my query had been resolved to which I immediately rep**** that it had not been resolved. I am yet to receive a response from them. It is almost a month now that I am waiting for delivery of my purchase. I want to know what the status of my order is but no one comes back to me with an answer. If they don't have the item in stock then I want a full refund. I am appalled by their level of service. This is the first and the last time that I purchase anything from Bradlows. I have made many online purchases from other companies and have received my purchases within a few days. If you can't supply me with what I ordered then refund me.
