Discovery Apple watch collection frustration

Activated and paid for my Discovery Apple watch on the 29th of June. Went to i-store the following day to collect, but due to a system error from discovery my activation code couldn't be sent to me. It was weekend so couldn't get hold of Vitality.

I returned on Monday only to be told that my payment code was no longer valid. I phoned vitality who could not assist me straight away and had to log a query.

I received feedback today (6 July) from Vitality who said that the problem was resolved and that my payment code had been reactivated. I went back to i-store only to find out that the payment code was not reactivated and hence still could not receive my watch. Immediately phoned Vitality who once again had to log a query.

3 trips to i-store after paying my activation fee and still no watch and no confidence that the problem is being resolved. This has been a terrible experience after I was promised a seamless process.
