Buffeting in intermitten transmission

*** -ref ********** 47A-Htuyca@4 I refer to the above matter and would like to inform you how dissatisfied I am with your service. Kindly trace my telephone calls made to the 10210 to try to resolve this matter and up to this day nothing is working properly. A technician was dispatched to my home but was not very clued up to identify the problem. Every time I phoned the call centre something was done in the background and the internet behaved for a short space of time. I am very tied of calling your call centre to resolve this matter please have this matter escalated as a matter of urgency.
