This afternoon I did receive a reply from OVO 'Samantha', however her response was totally unrelated to my issue and actually related to another issue which had previously been addressed.
However this evening I have received another wrong email from OVO which I have to say has left me speechless! I am truly astonished at the level of incompetence shown by OVO Customer services who seem incapable of answering questions without causing yet further issues..
Here is the offending reply I received this evening. To all concerned please note the following...
I am not leaving OVO for a new supplier nor have I told you otherwise.
At this current rate of poor service I might consider leaving, I'm sick of doing OVO's work for them when in actual fact they don't bother acting on their promises to put things right.
