Capitec placed a hold on my account

I use my Capitec account as a saving account,there is a decent amount in the savings account, i paid R1500 into the account 25 May and then on Monday 13 July i got an sms :A hold was placed on your account 14 Jul. Visit any branch with ID and proof of residence.... Now i have had this account for probably more that 5 years, why is it blocked now??? Without any reason, i called the call center and they couldn't help me.. So poor. <br> I cannot think of any valid reason for blocking my account and i think its nonsense that i have to now go to a branch to sort it out.
