Really dissatisfied seriously bad service

I sent my Huawei y91 in for repairs the battery was expanding and the phone was giving me a heads up the battery needs attention I sent a request for the postal repair service on the 1st of December 2025 because I needed a back up phone which only arrived the day before then I got notice it will be collected on the 3rd of December 2025 which never happened it got collected the 4th of December I had to follow up as no one contacted me about the delay I also packed the charger with the device upon request by the 9th I received a quote for replacement of the battery and I requested for the repairs to continue as I would be paid the 20th and will pay immediately for this to be done then 10th of december I had a missed call and I tried calling back with no luck of speaking to the person assisting me they said they will call back now I work in an environment where we are not allowed our cellphones on us while working so it made it hard for me to answer any calls yet I had no reply via email I also had a missed call the 17th but didn't get a chance to call back then all of a sudden Monday the 22nd the device was delivered back to me I was in shock thought it was repaired only to find this phone that I sent in working condition no longer even turns on I even flashed the device so that it was ready for the work to be done the battery was still working and even holding charge now when I get it I had to take it to another guy to repair and I had to then spend 1000 all together on replacing the battery and the Ic aswell I don't think this is very fair try calling only twice and not even replying to an email I sent and to have made the phone worse costing me more money this is the worst service ever
