Failure to resolve a data query after 7 phone calls and 2 reference numbers

<p>Vodacom allege data was used out of data bundle. The amount was queried several times. After 15 phone calls on my part and 2 reference numbers later (of which the first was cancelled without any resolution to me hence I followed up again as they allege they will make contact with you in 48 hours but to no avail) I am sitting with an exorbitant bill owing to vodacom. To date no one from data or collections have made contact with me despite my endless effort, barring a pre recorded automated system asking me WHAT payment arrangements I will be making. This is the second time this has happened only to have vodacom credit my account the first time. </p>
