Telkom *****s monthly data

My Wife & son entered into a contract with Telkom, under which he received 5gb of data per month. This was approximately 5 years ago.

Since then, his 5gb has disappeared, and he was told that they had "migrated his account to another type"

Fact is his data has disappeared . He now wants to port to FNB, but Telkom has blocked the port, despite a cancellation call and later email having been sent.

Seems Telkom is keen to get customers, but not so keen to release customers (the account is more than 1 month in credit) .
