Bad Service at alec autopage

In Dec 2015 I was called by one lady who is Altec Autopage consultant who called me regarding my cell phone upgrade(New cell phone) since my contract was due to expire.She gave me a choice of couple phones that would cause my normal instalment to be high I refused saying that I do not want to pay more than I was paying. She then offered me the Lumia 640 LTE at the same instalment that I was paying and also said that I will not be debited in Jan since there was a special, I then agreed to the offer .The Phone was never delivered in Dec 2015 , Jan 2016 until I phoned thier offices in Feb 2016 complaining about their service and yet they were debiting my account, I also complained about the fact that in Jan 2016 the debit went through yet they promised not to debit. After waiting for a long time to get my phone I eventually got the Phone late in Feb 2016 somewhere around the 21st .Upon getting my phone I waited to get my refund since I was promised that the issue of debiting in Jan is under investigation. Eventually I was credited R 180.00. yet on my account R274.50 was deducted. I was later migrated and the contract agreement changed without my knowledge and agreement. thank u
