wrong number

I am so sick and tired of the SABC. They are sending sms's for ME to a total stranger!!!! This person being a 76 year old pensioner. They still using my ****en surname as well. I have emailed them to tell them this but have since got no reply. The poor person receiving the SMS is so stressed out as he does not understand why he is receiving the SMS each month asking for payment. They better sort this!!!!
