St Courier — Delayed delivery, unprofessional behaviour

I had never chose this stupid service. But products i ordered had come through this carrier. And not even a single parcel had reached me on time. These stupids literally misbehave and take the CUSTOMERs for granted.
1. They call you and ask for address and they will never(as if address is not mentioned, asking way to the address is fine but…)
2. They never deliver on time, they always have the parcel with them minimum for three days.
3. For one product they asked me to collect(why the hell i have to pay shipping charges)
4. For the second time they took 6 days to deliver. Every time I get a call they ask the address and the delivery person will say “bike problem”, i wonder how come day after day each of their delivery partners get bike problem while delivering to me.
5. I would not use bad words, but all the bad words that exist in the world will go to these sons of ###.
They will soon close the operations as they are digging their own grave.
