horrible service and horrible product

I have purchased an Acer chromebook for my son for school as they state that all work would be done on the chromebook as to avoid unnecessary books being carried around. The chromebook was faulty and needed to be sent in for repairs which i took to Acer on the 22/01/2020. The chromebook has been in for repairs since the 22/01/2020 to date. Today i have called Acer *** to enquire the delay on the repairs. The consultant that i have spoken to Jimmy said its still in the quee to be fixed. I then asked for a manager he states that there is only a supervisor who will assist as there are no managers in the call centre. I then spoke to the Supervisor Luwellyn who said that his manager Fransoir is unavailable i then requested the head of the call centre as i need to sort this matter out today as this is not acceptable. i was then told that i cannot speak to the person in charge Dave as he would not take my call. As it stands i have paid for a chromebook that my child needs for school, Acer has been sitting with the laptop since the 22/01/2020 and has not bothered to fix it or treat it as a matter of urgency. I have been refused access to speak to the higher managers who might be able to resolve this query. Acer has taken the money very quickly when purchasing the laptop although when the laptop is faulty and under warranty they take there time to fix there faulty machinery. The service being received by them is absolutely horrible and the fact that you are being told straight forward you cannot speak to a manager may be the reason why queries are so far behind and are not being resolved! i would like a call back from "Dave" who is apparently the senior person in the call centre to have this matter resolved
