worst service goes all the way to headoffice

I failed to receive a package on time, 2 weeks ago. I had the worst customer service trying to get answers. I spoke to 4 different people in one call, none of which were helpful. I spoke to 2 supervisors who promised to get back to me but didn't. Eventually I had to order the item again go collect it myself and go through the trouble of having to cancel the other order and be content with a voucher for my return not cash. I did more work than the couriers they use to get a simple package. The worst part is that I complained to customer service and got blamed for their bad service. According to them my package was delivered but no one was home... first of all the delivery address was my work, where i am all day 8 until 7. This was the reason i was given for not being reimbursed for the time it took to be a courier for takealot for a day. since explaining this their customer service has ignored me. I had asked to speak to some one else and Ive been ignored again. I dont understand how it is possible for a company not to investigate a matter properly and blame a customer for their bad service based on information they didn't bother to validate. This is unprofessional and degrading.
