Makro online dept is extremely slow

I wrote an email to Makro to return a TV on 13 Jan 2025. I also marked the return on their website and followed the steps carefully. In addition I also contacted them through their Whatsapp line. No one could help me. Today is 20 Jan and it is still not sorted out! Mr Siphamandla Mthethwa was also of very little help, despite several emails. I asked them to call me since the 14 day return period is running out, but they are extremely slow in their response!
