Dissatisfied

Dstv consultants are failing to assist clients accordingly this the 10th I am calling them due them saying I haven't paid and I have and have sent proof of payment. The keep telling me to ignore the sms's but I get home my decoder is off. Please assist me as I have really been patient and I am a paying customer, and I always pay on time. I must have spoken to 7 consultants and I was told they will sort it out.
