Takealot communication and feedback is horrible

I ordered my husband replacement hollbrook Oakley lenses on the 4th of April. Received them and logged a return as it was the wrong size. Choosing the only criteria that I could to get a credit to order others because there was not such an option. It was picked up the next day and I received an email 2 or 3 days later they don't accept my return because of my criteria. So they sent it back with dpd and said I should choose no longer want item. I received it a few days later logged a return exactly like the lady on the email said. It was picked up the next day. Just to receive another email that the criteria is not right because if I didn't want it I should not have opened it. If I didn't open it I wouldn't have been able to check the size so I DONT WANT IT! Then agent no. 3 sent an email. And agent no 4. And agent no 5. So they decided without my permission after saying that they should send it back so I can log another return they decided to send it to returns department and try and sort it out from there. They don't respond to emails, the communication and feedback is absolutely horrible! It is nou 6 May and I don't have my new lenses, wrong lenses, credit or my money. I am disgusted in their poor client service.
