Bad customer service

I placed and order for retro bulbs that come in 2s and only 1 was delivered. I have sent more than 3 emails and had several more phone calls and takealot wants to collect the bulb I am using already instead of just delivering the other bulb. There is no escalation process as I have asked several times to speak to a manager and none seems to be available. They don't respond to emails(except the auto responses which are nonsensical) and don't provide you with a personal contact number or email address of one person that can help you resolve your issue. I am now waiting on a call back, but I am not holding my breath. There is no complaints link on their site I have been able to find. I can say I have had good service when things go right, but they can spend some time on resolving issues when things go wrong.
