Disappointed in the lack of service

My first installation was scheduled for Friday 3rd May between 8-10 am.Technician did not arrive. Called the call centre and I was told that feedback would be provided for me by the end of that day - no feedback received. Called Saturday - No assistance from the call centre. Monday 6th May, after being transferred to many different operators, I was eventually connected to Kim, the lady that handles my account. She informed me that she would follow up and return my call at 2pm, which did not happen.

Monday evening, Openserve called and arranged for a technician to do the installation the following day (Tue 7th May) Between 2-4pm. I was advised by my domestic that the technician was there at about 11 am, which was not the time agreed upon.

Very dissatisfied with the service and lack of communication.
