Data overcharged

We have a vodacom business account, we have 42 contracts with vodacom. Our account number is QC362135 and we have maintained a good record with business accounts. In the past 2 weeks one of our bills for ********** 5726 has hit a record of over R76000 on the data account. According to our knowledge, the consultant is an older person who has no idea how the data on a phone even works and uses only calls for business calls.

How on earth does data cost so much and never had we ever had such a high bill. Should this account not be credited we will be looking at another service provider and will cancel our contracts.

Please can I have vodacom contact me to discuss this matter urgently. My office number is ********** 000.

Many thanks Nancy Jaiputh (email: **********
