BAD Service from Vodacom

I went to Wonderboom junction Vodacom on the 02nd of May fro an upgrade. The person that assisted me Monica was very helpful when assisting me with the contract upgrade, when i was in store she was supposed to be make the changed she said that she cant give me a new contract with the changes and that it will be emailed to me. only on Monday when i looked at the vodacom app did i realized that there was problem , i phoned the shop and spoke to Given the manager who advised me that someone would phone me back to assist , when Monica phoned me back i also explained the problem with my account she said that she will not be able to assist me as they are busy with customers, Tuesday no one phone me. today 6 may i phone and spoke to Given from the store again and i advised him that the account is incorrect what i signed for was not loaded on the account, the data that was supposed to be removed was never done , the starting date of the contract was changed without telling me resulting in a bigger payment the end of the month , after explaining the problem he tried to cover for the staff for not doing the correct work and giving me the incorrect information. i asked him to make the correct changes, to email me the new contract the information of what was changed with an apology and he said that he cannot do this. this contact is null and void as the incorrect information was given to me and nothing is what i asked for on my account. When i asked who the regional or area manager is he advised that there is no one HOW CAN VODACOM not have a regional or area manager. there is also no COMPLAINTS department. this is disgusting service.
