Am having contract with Telkom, my account is up-to-date not on areas

Am having contract with Telkom, my account is up-to-date not on areas. Telkom decided to switch me off from using contract benefit without a reason, I can't sms I can't access my data,now is been 5 days experiencing this, I have tried to contact them in many ways with no Vain. Now I am spending unnecessary everyday to check up my loved once, meanwhile am paying contract each and every single month. I am not happy about their service.
