Bad service

Worst service ever, I am getting really frustrated now on the 20 July I sent my phone for repairs then a month later it was returned without being fixed because a consultant did not fill in the insurance forms then I went back the to tell them that it was not filled in then went signed and they returned it back for repairs then the 26 August got another message that I need to accept quote I call they told me again that a form was not attached and a consultant advised me that she filled it in and sent to repairs job number ***8 and told me they will send me another quote of how much I must pay now I get another message that they are returning it unfixed, I'm really getting fed up now I this is really an inconvenience to another level when you take my money you do not want any signature but now the tablet must be fixed you keep on sending it back, I want my phone fixed 2 months is a very long time
