St Courier — Critical complaint

I'm working in HP company. I need to replace hp printer to HP warehouse. I put my printer in ST courrier vandavasi on 22/9/23 afternoon they told it will take time upto evening to make docket. I made payment and came. Now it's been 1 week not even they created docket. I called more than 50 times no response and they blocking my calls. Very worst response. I'm in outlocation not even to visit the courrier office. Company gave me memo and billed the printer charge of Rs.20000 from my side and suspended me for this reason. What the hell are you servicing for customer. You spoiled my career. Because of you I'm in trouble. Trying customer care number not exist 😡. No words to shout at all. I'm completely done.
