Poor Service

My husband went to Vodacom Chatz (East Rand Mall) on 12/12/2015 to get a contract on a tablet, his son needs it for school. They told him that they will need three months bank statements, He took the bank statements to them on 16/12/2015. He ask them when will he be notified on the contract, they told him in four hours time. On 28/12/2015 he call Sandra but she was not in and nobody called my husband back. My husband call again on the 29/12/2015 to find out what is going on. The y told him that they have misplaced his bank statements and that they think it is at one of the employers house, but they will let him know. Today (07/01/2016) he went to the shop and they told him that can't find his bank statements. He then asks why didn't any body call him to tell him this. My husband feels very unsatisfied with the service and feedback from Vodacom Chatz.
