Complaint regarding upgrade request and contract discrepancies

I am writing to express my disappointment and frustration with the service I received on June 4th when I requested an upgrade. The consultant I spoke with assured me that the package would include an additional SIM card, which was not the case. Furthermore, I was told that the outstanding amount would be paid over three months, after which my initial contract would commence. However, when I called today, I was given a different story.

I am extremely dissatisfied with the misinformation and inconsistencies in my contract. I request that you investigate this matter and rectify the issues as follows:

- Provide the additional SIM card as promised - Honor the payment arrangement agreed upon (three months) - Ensure that my initial contract terms are upheld

I would appreciate a prompt resolution to this matter. Please contact me at your earliest convenience to address my concerns.
