Poor custome care

I'm very disappointed by We buy cars customer care, ( Blake Mitchell) he is consultant supposed to be assisting me. I bought a car two week ago from We buy cars and I opted for a warranty option and unfortunately week a after purchasing a car I started get Drivetrain error msg and I was advised to launched a complain to we buy cars for further assistance. And the consultant indeed contacted me to understand the issue and he advised me to take my car to any approved rmi workshop for diagnostics which I did and emailed back the findings. Therefore what leaves me so disappointed is the fact of bad communication, they are not even coming back to me to advise that they acknowledged the email and also advise with a way forward
