Dispute with Mobiles.co.uk and Vodafone over duplication of contracts. On 4 July 2019 @18:30, I ordered a Samsung S10 phone on a two year Vodafone contract from Mobiles.co.uk. Four days later the original SIM number was changed to my personal number by Vodafone. The day after that the phone developed a fault and was subsequently sent back to Mobiles.co.uk, who apparently requested Vodafone terminate the contract on 10 July (well within the cooling off period of 14 days). However, I was not made aware my contract had been terminated until I called Mobiles.co.uk on 19 July, and after my first monthly payment of £24 for that contract had been taken by Vodafone. Mobiles.co.uk advised me that as they had terminated my contract of 4 July with Vodafone, I should order a new phone with new Vodafone contract from them, and this I did on 19 July, and received my new phone with Vodafone SIM card and number on 20 July. However, as my personal number continued to receive calls, I emailed Mobiles.co.uk asking why, and they replied that the termination of 10 July had in fact failed and that I should contact Vodafone about this! On talking to Vodafone, they told me they could do nothing without Mobiles.co.uk authority to terminate the contract, ignoring the fact that Mobiles.co.uk, had already done so on 10 July. Despite going to Vodafone shops and subsequent calls to Vodafone customer services, they refused to do anything about the situation of my two contracts with them. By this time I had realised that on 10 July, Mobiles.co.uk had asked Vodafone to terminate the original number and not my personal number which is why my original contract was not terminated. This was negligence on the part of Vodafone who terminated an in active number, and did not consult their records that they had changed this to my personal number! Despite this information Vodafone continued to refuse to resolve the matter, essentially blaming Mobiles.co.uk lack of communication. On 26 July, Mobiles.co.uk promised to escalate the termination within 3-5 days, but this never happened. On chasing this on 3 August Mobiles.co.uk told me to get a PAC code from Vodafone to port my personal number out, and that after that I would receive a final bill with my termination fee attached from Vodafone. Furthermore that I should send the fee to Mobiles.co.uk so they could have the funds raised to cover this expense . Vodafone refused to give me a PAC code, but on 4 August @ 09:45 they did say they would at last terminate my first contract for an early termination fee of £431.83. This was of course unacceptable to me when it was partly their negligence that was to blame, and when I emailed Mobiles.co.uk to ask them to confirm they would reimburse this fee should I pay it, and when they would reimburse me, they ignored me! It is clear that there has been negligence on both the part of Mobiles.co.uk and Vodafone that has led to this situation. In addition Vodafone has been deliberately unhelpful throughout. Furthermore, as there is a cooling down period of 30 days when the mobile phone is faulty, both Mobiles.co.uk and Vodafone should have easily terminated the contract within that time frame. Indeed, at the precise time when Vodafone demanded that I pay them the early termination fee, it was chronologically within that 30 days (if you take each day to be 24 hours from the time I placed the order with Mobiles.co.uk) and therefore Vodafone may be breaking the law!
