Dotzot — No tracking details and more than 10 days I didn't where's my parcel

Hi,

I purchased a pet bed chew proof from jaipur online 10th May to salem, Tamilnadu. After payment seller provided tracking number R44777427 dtdc dotzot
But when I check with tracking number, it shows error and nothing found. I contacted seller and seller also registered complaint. When I asked in dotzot customer care they replied that tracking details are not uploaded by booking branch office and they asked me to talk to branch booking office in jaipur, when I tried contacting they didn't reply and asked me to contact different people everything without providing me parcel details.
