Neglected customer care/Bridge of contract by telkom

I currently have a contract mobile router with telkom, they deduct their money direct from my account and they never miss doing so. I have nor received my data for the months of April, as a result I am already feeling the impact of this with my business . I have for several times tried to contact telkom without success. The lines keep saying "all consultant are busy" you can hold for more than two hours waiting for someone take your query, please help.
