Return Equipment Issue

I have read several posts regarding my issue most of which are from last year so asking now so it is recorded on the Forum. Like others I have left VM towards the end of November. VM advised they would send packaging - they did not and then asked me to return immediatley or I would be charged - I advised no packaging had been received and they advised new packaging would be sent out - No packaging was received and the same thing happened. This time though they suggested the equipment could be picked up by VM - I chose that option.

Twice so far, I have waited in all day for VM to pick up their kit and twice they haven't turned up - the first time I received an apology by text and the second, I didn't. I have since received two cumulative bills requesting payment for not returning their kit. Please advise on what I can do now to return this kit.

I have several emails and texts to prove all this but the issue I have with (now) with returning via packaging is that they sent me a list of the kit and the serial numbers of the Hub5 don't match - simply as theyt replaced my Hub 5 ages ago and clearly didn't update it but i am worried in case they play silly beggers when they receive my kit. If the kit is collected however, I can explain this to the collector.   Many thanks in advance.
