Don't take a contract at telkom

Last month with my new contracts my line was suspended 8 times I went to the telkom store and was told I exceeded my credit limit I must make a payment of R900 to reactivate my account after a argument it was reconnected now I went to the store for my bill and was told that my account is fixed and I must pay 2270 or something like that I made a eft payment for the amount waited 4 days now the 900 is back on my account and I skipped a payment in August that I have proof of payment for poor service
