Bad Service

I opened a contract with vodacom in early May, at first the confirmation of my order took longer than expected. Every time i called it wouldve been that day but never was. I eventually got my order, they then tried to debit money from my account on the 19th and then on the 25th again after i choose the 1st as my debit order date, they also gave me a penalty for the unsucessfull debits from my bank. They also never informed me of this and why they tried to debit from my bank on the 19th and 25th. I am very unhappy with their service.
