Poor service delivery

It's a month dealing with Hauwei repair centre in Johannesburg I have spoken to them a few times regarding my screen that needs to be replaced did the live chat spoken to customer care a few time requested a supervisor to call back regarding delays on phone collection which took over a week got an email quotation which I was not told prior in my conversation didnt reject the quote some lady that called me was meant to do some follow up or listen to the call recordings regarding price quoted it's 2 week she didn't get back to me. Received an email yesterday regarding the quote and the fee charged if I decided not to go ahead with the repair. I rep**** to the email and full now not a single person has responded and this is something I said became urgent after the delay in collection of the phone. I was told by Sam the second consultant I spoke to that my log for collection was not attended to this was after the first week of me booking the device it. Somehow don't think that their customers are important to them yet the support they get from us as clients should be priority without customers there will be no business for them it's something they should look into and give first grade customer service. So hopefully someone will call me regarding the urgency of the matter at hand and poor service delivery.
