Vacuum returned incomplete

I've send my Bissell vacuum in for repairs on 08/01 as it is still under guarantee.When I went to collect my vacuum on 07/02, I saw it came back from repairs incomplete, only the part with the motor was returned whereas they took the front nozzle part and the filter. It was promised I'll have feedback on Mon 08/02 whereas I had to phone Game to follow up. Charles promised to give me feedback on Tue as he still didn't have an answer for me, still he didn't phone me. I phoned again on 12/02, still he doesn't have an answer for me and said he'll phone me within the next hour. Today is 15/02 and I'm still waiting for feedback. How can you send in something and then only half the items gets send back and then you sit with the inconvenience of waiting to hear what is going on and when can you expect your item. The day I took my vacuum for repairs, nobody informed me to keep the other parts, it was taken and now it is nowhere to be found.
