Meanwhile BT has taken £30 and £25 from my bank account, presumably for the upfront payment and the first monthly payment, although each was higher than the sums quoted on the phone.
Shortly after I contacted BT you picked up three telephone messages and an email from the company. It still took time for this to be sorted out though.
It turns out that BT sent the mobile and subsequently a cheque to an address in a street two miles away, albeit with a similar postcode.
At last it paid you £150, made up of the £55 taken from your account and £95 for goodwill.
Although BT did offer to send the phone and keep you on the contract, you now have a contract with another provider.
