I'm shocked at the terrible service

Where do i even begin. After 15 years being a Dstv premium member with a debit order. Ijust get cut off 3 weeks ago without warning. After phone call after phoncall to the call centre they told me the issue is on there side and opoligised to me promised it will be on within 24 hrs. 3 days later i phone back to find out why i was never connected. They then say i owe them 8k cause my debit order was stopped 10 months ago. I asked them who stopped it and they could tell me. I then checked my banking and could see this was correct. I then payed 10k into dstv acount mailed them pop and then called the call center again. they told me all was in order i had 2k odd credit and ill be reconnected within 24 hrs. Well that was 8 days ago and still nothing. I called them today only to be told my account is under investigation for ***** and they will contact me to find out what to do. How is this possible? I feel this is extremely unprofessional. i have spoken to 5 different agents today all say there is nothing they can do. Is there anyone that can give me light here. Only thing i can do at this stage is just open a new account in my wife's name cause im getting no where with DSTV. After 15 year not missing 1 payment i get trated like this. Shocking.....
