Insecure and unsatisfactory service from Vodacom

On the 19th October I was de*****ed on my Absa account. At the exact same time Vodacom Business Solutions blocked my phone!!!! Absa had to ring on my landline. When questioned Vodacom had NO EXPLANATION so the line was unblocked!! On the 24th October I rang to give Vodacom my new card info so that my debit order could be paid on the 31st. It took 25mins for them to take down the info and cost me R35 on my landline as the call center has such loud background laughing and shouting that I did not use my cell phone. Guess what? info not done and debit returned unpaid. The number on the sms is the wrong number to phone???? I insisted on speaking to a manager Amdami who promised to sort it and ring me back. Never happened. After every call an sms comes through that a Solution Expert will ring me. Never happens. Some expert!!!The blocking of my line has been reported to Vodacom ***** but I don't hold out much hope of an explanation or an apology. They now expect to upgrade !!!!! After such shoddy service????
