Samsung Smart Care Service Centre - poor turnaround times.

I dropped my Galaxy Tab off at the Samsung Smart Care Service Centre on the 24th Feb 2018 and I was told I would receive a quote for the repairs to my damaged screen within 5 days. It is more than 2 weeks later and I still have had no communication. When you phone them 9 times out of 10 the phone will ring and ring. When I finally got through yesterday I was promised that I would receive a quote by the close of business. I still have not received a quote.
