Terrible Service

A few weeks back I app**** for a cellphone contract. Upon application I requested that my existing prepaid number be used for the contract. I got the phone only to realize that my prepaid number had not been converted to contract. I then called the call centre numerous times to query this and get it sorted. The call centre told me to go to a Telkom Mobile shop ad they will be able to put the contract on my existing number. At the Telkom Shop I spoke to a guy who advised that only the Technical Services department can sort this out and he is lodging a query with them and he promised to get back to me within a day. Its been a week + and I haven't heard anything from anyone. Can someone please get this sorted out soon as it is inconveniencing me. I paid for a service which im not getting. I haven't been able to use this phone because there is no data or airtime in it and changing numbers is not an option.
