Ajio — Ajio system problem not collecting the product

Placed return on 9th Jan... Courier collected on 10th Jan.. next courier person gives it back coz his saying Ajio system problem and can't show picked up so said raise it again.
Msged Ajio customer care chat, they said they will sort it before or by 14th... No reply so 15th again msged them on chat they come back saying given another 2 more days.. till now no reply today's 17th Jan.
No customer service only chat from 12 pm to 8pm which makes it really disturbing...
