Uneducated Vodacom service

Vodacom offers a typical BBBEE service. They are totally uneducated, ******** and arrogant. For the past 8 years have I recharged my cell with R 500 per month for Data. Three months ago I received a message stating that I own them R 14 for advance services, that I should recharge my account before losing the services of Vodacom. Every month is my account recharged with R500 and VODACOM failed to deduct this R 14. Now for the second month, after the R 500 worth of data is exhausted are they suspending my services. I cannot by data, airtime on my number. I will now, from the end of the month change my services to MTN. Vodacom will loose a R 500 per month income for R 14 they neglected to deduct. The stupid nuts
