Service totally pathetic

Cellc customer care service is substandard to say the least.I was on the line with them for over an hour today.Trying to sort out a faulty tablet I purchased on my contract.I got shunted around from dept to dept.Most times be told they cannot hear me my line is bad.Before that had spoken to other people from the same phone and was heard very clearly.The people on the line from cellc were totally ***********.They have no interest in what they doing .I live in Ladysmith KZN the cellc store was closed down here.So now I'm sitting with a problem faulty tablet and battling to havecit retuned to cell c.Can a member of management from cellc contact me regarding this issue.
