Poor Quality and Bad customer service from Havaianas Cape Town

I would just like to express my disappointment in the customer service I received about the bad quality of your flip-flops. I sent an email on Thu, Nov 29, 2018, 9:02 AM and I received feedback that I was not happy with. I then responded the same day. I did not receive any feedback the sent another email Dec 6, 2018, 12:29 PM and still no feedback. When I called today ***:01 and spoke to Jody Van Der Merwe who I have been dealing with I was told that she responded to my 1st email and did not respond to the other emails as she already gave me feedback. Really? If I am paying in excess of R350 for a pair of flip-flops I expect a quality product and at least the decency of your company to answer my emails. I have been loyally purchasing your product and recommending it, but to pay R350 for a flip flop to break 5months later due to poor quality and not wear and tear is unacceptable.
