UNFAIR CUSTOMER TREATMENT

I am very disappointed on how Vodacom service is. I have been their client for 9 years. My cellphone acc was suspended and the problem started when they fail to debit my account when funds were sufficient on my bank account. I sent my bank statement to proof that but, no one responded. I paid my ACC IN FULL ON 7 JAN 2021, the amount of R3183 up to date they haven't re-instated my service. I have phoned 3 times, sent proof of payment to the manager and to POP... email address. I called again today and the Agent told me that I have to wait for another 24 hours.

IS IT REALLY FAIR?
