Bad customer service

I have a problem with finrite, I sent my phone to them 7 weeks ago and whenever I call them, they put me on hold for 15 mins and drop the call without coming back to me with feedback. The other lady, Thobela Keith, I gave her my cell number and she said she will follow up and get back to me, she never did. I escalated the matter and the query was forwaded to Andile Mkwa****, he has not responded to my emails for the past 3 weeks, together with his colleagues(Natasha Claasen & Leilane Ferris). Finrite has a very bad customer service, my wife had a similar problem when she sent her phone for repairs.
